a stand disposed at a first side surface of the display panel; a blowing fan disposed inside the stand; and a duct disposed at a second side surface of the display panel and connected to the stand. ## Claims ### Claim 1 A display device comprising: a display panel; a stand disposed at a first side surface of the display panel; a blowing fan disposed inside the stand; and a duct disposed at a second side surface of the display panel and connected to the stand, wherein the blowing fan is disposed under the display panel, and air discharged from the blowing fan passes through the duct and is provided on the entire rear surface of the display panel. ### Claim 2 (depends on 1) The display device of claim 1, wherein the stand includes: a body part in contact with the first side surface of the display panel; and a lower end connected to the body part. ### Claim 3 (depends on 2) The display device of claim 2, wherein: the blowing fan is disposed in the lower end. ### Claim 4 (depends on 2) The display device of claim 2, wherein: a length of the body part in a first direction is substantially the same as a length of the display panel in the first direction. ### Claim 5 (depends on 1) The display device of claim 1, wherein the duct includes: a first injection hole providing a passageway to an inside of the stand; a first passage extending along a first direction; and a first outlet connected to the first passage. ### Claim 6 (depends on 5) The display device of claim 5, wherein the first passage is stream-lined. ### Claim 7 (depends on 5) The display device of claim 5, wherein the first passage has a semi-circular or a semi-elliptical shape. ### Claim 8 (depends on 5) The display device of claim 5, wherein the first passage has a shape that becomes narrower as its upper portion is approached. ### Claim 9 (depends on 5) The display device of claim 5, wherein a width of the first injection hole is larger than a width of the first outlet. ### Claim 10 (depends on 5) The display device of claim 5, wherein the length of the first outlet in the first direction is substantially the same as the length of the display panel in the first direction. ### Claim 11 (depends on 1) The display device of claim 1, further comprising: a circuit board connected to the display panel and disposed at the second side surface of the display panel; and a second side surface housing covering the circuit board and the duct. ### Claim 12 (depends on 11) The display device of claim 11, wherein the second side surface housing includes a hole. ### Claim 13 A display device comprising: a display panel; a stand disposed at a first side surface of the display panel; a blowing fan connected to the stand; and a duct disposed at the rear surface of the display panel and connected to the stand, wherein the duct includes a first injection hole providing a passageway to the stand, wherein air flows through the first injection hole; and a first discharge hole through which the air, from the first injection hole, flows out of, and wherein the blowing fan is disposed under the display panel, and air discharged from the blowing fan passes through the duct and is provided on the entire rear surface of the display panel. ### Claim 14 (depends on 13) The display device of claim 13, wherein the duct extends along a first direction, and a length of the duct in the first direction is substantially the same as a length of the display panel in the first direction. ### Claim 15 (depends on 13) The display device of claim 13, wherein the stand includes: a body part in contact with the first side surface of the display panel; and a lower end connected to the body part, wherein the blowing fan is disposed at the lower end. ### Claim 16 (depends on 13) The display device of claim 13, wherein the duct further includes a first passage connecting the first injection hole and the first discharge hole to each other. ### Claim 17 (depends on 16) The display device of claim 16, wherein the first passage has a streamline shape, a semi-circular shape, or a semi-elliptical shape. ### Claim 18 (depends on 16) The display device of claim 16, wherein the first passage includes an upper portion and a middle portion, wherein the upper portion is narrower than the middle portion. ### Claim 19 (depends on 13) The display device of claim 13, wherein a width of the first injection hole is larger than a width of the first discharge hole. ### Claim 20 (depends on 13) The display device of claim 13, further comprising: a circuit board connected to the display panel and disposed at the rear surface of the display panel; and a rear surface housing covering the circuit board and the duct, wherein the rear surface housing includes a first hole and a second hole.
