Abstract: A display apparatus capable of improving heat-dissipation performance while not increasing a total thickness thereof include a heat-dissipation member accommodated in a cushion plate. Thus, the heat-dissipation performance may be improved without increasing a thickness of the display apparatus. Thus, a mounting space for components may be secured without increasing a bezel area. Further, the heat-dissipation member having a predetermined thickness and an air gap are disposed in the heat-dissipation member accommodating space of the cushion plate, thereby maximizing the heat-dissipation from a driving integrated circuit disposed under the cushion plate so as to overlap the heat-dissipation member accommodating space.

Abstract: Disclosed are a display module and a display device capable of minimizing a pressed stain defect while reducing a bezel area. To this end, a thickness of a cushion portion of a cushion plate closer to a bent portion may be reduced, thereby reducing a bending radius of curvature such that the bezel area may be reduced. Further, placing a support layer having a strong supporting force formed of PET into the cushion plate such that the support layer is in contact with the heat-dissipation layer may allow minimizing an unevenness defect on the cushion plate even when a bent pad portion of a display panel presses the cushion portion. Thus, visibility of an internal pressed stain to a user may be minimized.

Abstract: A display device comprises: a backlight unit; a liquid crystal panel comprising a lower polarizer, an upper polarizer, and a first substrate and a second substrate; and a cover plate on the liquid crystal panel, wherein a camera hole passes through the backlight unit and up to the lower polarizer, an interference prevention hole is located at a position corresponding to the camera hole, and the camera hole is not in the first substrate and the second substrate. The display device has a hole with a uniform size, decreased processing cost, increased structural rigidity, and does not have thermal deformation, can prevent defects such as generation of air bubbles, bending deformation, and distortion of a light path due to the hole and the vacuum bonding while increasing the visible light transmittance and resolution of the camera, and improving the appearance quality of the display device.
