a first film disposed on the display panel, and including a second side surface; a second film disposed under the display panel, and including a third side surface; a first adhesive layer disposed between the display panel and the first film; and a second adhesive layer disposed between the display panel and the second film, wherein the first side surface is a first portion of an outmost surface of the display panel, and at least a portion of the second side surface and at least a portion of the third side surface protrude more to a side in a lateral direction than the first side surface. ### Claim 2 (depends on 1) The display module of claim 1, wherein the first side surface of the display panel, the second side surface of the first film, and the third side surface of the second film are disposed parallel to each other in a thickness direction of the display module. ### Claim 3 (depends on 2) The display module of claim 2, wherein a side surface of the first adhesive layer and a side surface of the second adhesive layer have a shape inclined with respect to the thickness direction of the display panel. ### Claim 4 (depends on 1) The display module of claim 1, wherein the second side surface of the first film and a side surface of the first adhesive layer are connected to each other, and the third side surface of the second film and a side surface of the second adhesive layer are connected to each other. ### Claim 5 (depends on 1) The display module of claim 1, wherein a maximum width between the first side surface of the display panel and the second side surface of the first film is at least about ¼ times a thickness of the display panel, in a plan view. ### Claim 6 (depends on 1) The display module of claim 1, wherein an entire side surface of the display panel overlaps the second film and is overlapped by the first film, in a plan view. ### Claim 7 (depends on 1) The display module of claim 1, wherein the display panel further comprises a side surface spaced apart from the first side surface, the side surface is a second portion of the outmost surface of the display panel, and the side surface is aligned with the second side surface and the third side surface. ### Claim 8 (depends on 1) The display module of claim 1, wherein an inclination of the second side surface of the first film with respect to the first side surface of the display panel is constant, and an inclination of the third side surface of the second film with respect to the first side surface of the display panel is constant. ### Claim 9 (depends on 1) The display module of claim 1, wherein an inclination of the second side surface of the first film with respect to the first side surface of the display panel varies depending on a position in the second side surface, and an inclination of the third side surface of the second film with respect to the first side surface of the display panel varies depending on a position in the third side surface. ### Claim 10 A display module comprising: a display panel including a first side surface; a first film disposed on the display panel, and including a second side surface; and a second film disposed under the display panel, and including a third side surface, wherein at least one of the second side surface of the first film and the third side surface of the second film protrudes more by a protruding width than the first side surface of the display panel, and the protruding width is about ¼ to about 3 times a thickness of the display panel. ### Claim 11 (depends on 10) The display module of claim 10, further comprising: a first adhesive layer disposed between the display panel and the first film; and a second adhesive layer disposed between the display panel and the second film, wherein the first side surface of the display panel, the second side surface of the first film, and the third side surface of the second film are parallel to each other in a thickness direction of the display panel, and a side surface of the first adhesive layer and a side surface of the second adhesive layer each have a shape inclined with respect to the thickness direction of the display panel. ### Claim 12 (depends on 10) The display module of claim 10, wherein an entire side surface of the display panel overlaps the second film and is overlapped by the first film, in a plan view. ### Claim 13 (depends on 10) The display module of claim 10, wherein the display panel further comprises a side surface spaced apart from the first side surface, each of the first side surface and the side surface is an outmost surface of the display panel, the first side surface is more protruding than each of the second and third side surfaces, and the side surface is aligned with the second side surface and the third side surface. ### Claim 14 (depends on 1) The display module of claim 1, wherein the display panel includes an active area and a peripheral area surrounding the active area, and the display panel further includes a driving circuit disposed in the peripheral area to drive the active area. ### Claim 15 (depends on 1) The display module of claim 1, wherein the third surface of the second film protrudes laterally from the first side surface of the display panel by a distance in a range of about 0.25 to about 3.0 times a thickness of the display panel. ### Claim 16 (depends on 10) The display module of claim 10, wherein the first side surface is an outmost surface of the display panel.
