Abstract
A display module and a display device which can improve a heat-dissipation performance and a shock absorption function while reducing a bezel area include a cushion plate with a metal foam that has both a heat-dissipation function and a cushion function, so that both of an effective heat-dissipation function and an effective cushion function can be realized only using the metal foam without addition of a separate heat-dissipation layer or cushion layer. Further, the metal foam of the cushion plate has very excellent heat-dissipation function and cushioning function at only a small thickness thereof, so that a total thickness of the cushion plate can be greatly reduced, and the bezel area can be reduced.
