The display device includes a first substrate, a second substrate positioned opposite the first substrate, a seal member which attaches the first substrate to the second substrate and seals a display area positioned on the first substrate or the second substrate, and a plurality of pixels which are positioned in the display area and each include an organic light emitting layer. Each of the first and second substrates includes two first straight sides extending in a first direction, two second straight sides extending in a second direction crossing the first direction, and four edges where the two first straight sides and the two second straight sides intersect. The four edges of each of the first and second substrates are formed as curved edges. ## Claims ### Claim 1 A display device comprising: a first substrate; a second substrate positioned opposite the first substrate; a seal member configured to attach the first substrate to the second substrate and seal a display area positioned on the first substrate or the second substrate; and a plurality of pixels positioned in the display area, each of the plurality of pixels including an organic light emitting layer, wherein each of the first substrate and the second substrate includes two first straight sides extending in a first direction, two second straight sides extending in a second direction crossing the first direction, and four edges where the two first straight sides and the two second straight sides intersect, wherein the four edges of each of the first substrate and the second substrate are formed as curved edges. ### Claim 2 (depends on 1) The display device of claim 1, wherein the display area includes a first pixel unit including m pixels arranged in the first direction and n pixels arranged in the second direction, where ‘m’ and ‘n’ are a positive integer equal to or greater than 3, and a second pixel unit including pixels, of which the number is less than ‘m’, arranged in the first direction and pixels, of which the number is less than ‘n’, arranged in the second direction. ### Claim 3 (depends on 2) The display device of claim 2, wherein the second pixel unit is positioned in an area adjacent to the curved edges. ### Claim 4 (depends on 2) The display device of claim 2, wherein the display area includes the two second pixel units. ### Claim 5 (depends on 2) The display device of claim 2, wherein each of the curved edges includes a circle or an oval. ### Claim 6 (depends on 5) The display device of claim 5, wherein a radius of curvature of the circle forming the curved edge is about 5 mm to 35 mm. ### Claim 7 (depends on 5) The display device of claim 5, wherein the four edges of the first substrate coincide with the four edges of the second substrate. ### Claim 8 A display apparatus comprising: a display device including a plurality of edges formed as curved edges and straight sides connecting the curved edges; a back cover coupled to a back surface of the display device; a rear cover coupled with the display device and the back cover, the rear cover having four edges formed as curved edges of the same shape as the curved edges of the display device; a lever member including a housing fixed to the back surface of the display device or a back surface of the back cover and a lever slidably installed inside the housing; and a sliding member including a guide positioned on a front surface of the rear cover and a sliding bar which is slidably installed on the guide, contacts the lever when the lever slides, and is used in the position movement. ### Claim 9 (depends on 8) The display apparatus of claim 8, wherein the housing is positioned at the curved edges of the display device, and the guide and the sliding bar are positioned on the front surface of the rear cover opposite the straight sides of the display device. ### Claim 10 (depends on 9) The display apparatus of claim 9, wherein the housing includes a guide block forming a guide rail having a curved part and a cover coupled with the guide block, wherein the lever of the lever member is coupled with the guide rail. ### Claim 11 (depends on 10) The display apparatus of claim 10, wherein the lever includes a body coupled with the guide rail and a handle coupled with the body. ### Claim 12 (depends on 11) The display apparatus of claim 11, wherein the cover of the housing has a hole, to which the handle of the lever protrudes. ### Claim 13 (depends on 12) The display apparatus of claim 12, wherein the handle protrudes to the outside of the housing through the hole at a sliding start position of the lever, wherein the handle is entered into the housing and does not protrude to the outside of the housing through the hole at a sliding end position of the lever. ### Claim 14 (depends on 13) The display apparatus of claim 13, wherein the guide block includes a protrusion capable of fixing and sliding the lever at the sliding start position and the sliding end position of the lever, wherein the lever includes a groove, into which the protrusion is inserted. ### Claim 15 (depends on 13) The display apparatus of claim 13, wherein the sliding bar slides along the guide by a sliding operation of the lever, and one end of the sliding bar is coupled with the housing when the lever is positioned at the sliding end position. ### Claim 16 (depends on 15) The display apparatus of claim 15, further comprising a middle cabinet covering the side of the display device, the middle cabinet covering the straight sides of the display device. ### Claim 17 (depends on 16) The display apparatus of claim 16, further comprising an auxiliary middle cabinet covering the curved edges of the display device, the auxiliary middle cabinet covering the curved edges of the display device in a state where the lever is positioned at the sliding end position. ### Claim 18 (depends on 8) The display apparatus of claim 8, wherein the display device includes: a first substrate; a second substrate positioned opposite the first substrate; a seal member configured to attach the first substrate to the second substrate and seal a display area positioned on the first substrate or the second substrate; and a plurality of pixels positioned in the display area, each of the plurality of pixels including an organic light emitting layer, wherein each of the first substrate and the second substrate includes two first straight sides extending in a first direction, two second straight sides extending in a second direction crossing the first direction, and four edges where the two first straight sides and the two second straight sides intersect, wherein the four edges of each of the first substrate and the second substrate form the curved edges of the display device. ### Claim 19 (depends on 18) The display apparatus of claim 18, wherein the display area includes a first pixel unit including m pixels arranged in the first direction and n pixels arranged in the second direction, where ‘m’ and ‘n’ are a positive integer equal to or greater than 3, and a second pixel unit including pixels, of which the number is less than ‘m’, arranged in the first direction and pixels, of which the number is less than ‘n’, arranged in the second direction. ### Claim 20 (depends on 19) The display apparatus of claim 19, wherein a radius of curvature of a circle forming the curved edges of the first and second substrates is about 5 mm to 35 mm.
