at least one first sound generator on a rear surface of the display panel; and at least one second sound generator in the non-display area, the at least one second sound generator being asymmetrically disposed with the at least one first sound generator. ### Claim 2 (depends on 1) The display apparatus of claim 1, wherein the at least one second sound generator is disposed at an upper portion rather than the at least one first sound generator. ### Claim 3 (depends on 1) The display apparatus of claim 1, wherein the at least one second sound generator is provided as a plurality, one of the plurality of second sound generators is disposed at different positions with respect to the at least one first sound generator. ### Claim 4 (depends on 1) The display apparatus of claim 1, wherein the non-display area includes four-side peripheries of the display area, and the at least one second sound generator is provided as a plurality, the plurality of second sound generators are on at least one or more sides of the four-side peripheries. ### Claim 5 (depends on 1) The display apparatus of claim 1, wherein the at least one first sound generator generates sound of middle and high-pitched sound ranges and the at least one second generator generates sound of high-pitched sound ranges. ### Claim 6 (depends on 1) The display apparatus of claim 1, wherein the at least one first sound generator includes a coil type sound generator, and the at least one second sound generator includes a piezoelectric sound generator. ### Claim 7 (depends on 6) The display apparatus of claim 6, wherein the coil type sound generator comprises: a plate; a magnet and a center pole on the plate; a bobbin around the center pole; and a coil near the bobbin. ### Claim 8 (depends on 1) The display apparatus of claim 1, further comprising: a light guide member on the rear surface of the display panel; and a supporting member on the rear surface of the display panel, and wherein the at least one first sound generator is between the light guide member and the supporting member. ### Claim 9 (depends on 8) The display apparatus of claim 8, further comprising: a sheet portion on the rear surface of the display panel, the sheet portion being spaced apart from the light guide member. ### Claim 10 (depends on 8) The display apparatus of claim 8, further comprising: a sheet portion on the rear surface of the display panel, the sheet portion being extended to the non-display area. ### Claim 11 (depends on 8) The display apparatus of claim 8, further comprising: a sheet portion on the rear surface of the display panel, the at least one second sound generator being on a rear surface of the sheet portion. ### Claim 12 (depends on 11) The display apparatus of claim 11, further comprising a pad between the sheet portion and the at least one second sound generator. ### Claim 13 (depends on 1) The display apparatus of claim 1, further comprising a structure on a rear surface of the at least one second sound generator. ### Claim 14 (depends on 13) The display apparatus of claim 13, wherein the structure is on a side surface of the at least one second sound generator. ### Claim 15 (depends on 13) The display apparatus of claim 13, further comprising: a supporting member on the rear surface of the display panel; and a connection member between the structure and the supporting member. ### Claim 16 A display apparatus, comprising: a display panel including a display area configured to display an image and a non-display area, the display area having a first area and a second area; at least one first sound generator on a rear surface of the display panel and being in each of the first area and the second area; and at least one second sound generator in the non-display area, the at least one second sound generator being asymmetrically disposed with the at least one first sound generator. ### Claim 17 (depends on 16) The display apparatus of claim 16, wherein the at least one second sound generator is disposed at an upper portion rather than the at least one first sound generator. ### Claim 18 (depends on 16) The display apparatus of claim 16, wherein the non-display area includes four-side peripheries of the display area, and the at least one second sound generator is provided as a plurality, and the plurality of second sound generators are on at least one or more sides of the four-side peripheries. ### Claim 19 (depends on 16) The display apparatus of claim 16, further comprising a partition near the at least one first sound generator in each of the first area and the second area. ### Claim 20 (depends on 16) The display apparatus of claim 16, further comprising a partition surrounding the at least one first sound generator in each of the first area and the second area. ### Claim 21 (depends on 16) The display apparatus of claim 16, further comprising: a partition near the at least one first sound generator in each of the first area and the second area; and a bent portion bent toward the at least one first sound generator in at least one or more sides of four sides of the partition.
