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 has an anti-static layer extending from a cover member along a side surface of a display panel to an inner surface of a hole of a cushion plate. Thus, a contact area between the anti-static layer and the display panel may be increased, thereby reducing a brighter phenomenon and a greenish phenomenon at a distal end of the display panel.

Abstract: The present disclosure relates to a display panel and particularly to a display panel including a backplate disposed below a panel layer and having a pattern forming area in which groove patterns are formed on both sides. Disclosed is a display panel including: a cover window including curved areas formed on both sides and a flat area formed in a middle; an adhesive layer disposed below the cover window; a panel layer disposed below the adhesive layer; and a backplate disposed below the panel layer and including pattern forming areas formed on both sides and a non-pattern area formed in a middle, and the backplate includes a plurality of groove patterns disposed in a first direction and extending in a second direction in the pattern forming area.
