Abstract: A display device includes an encapsulating structure disposed on an array substrate, a bottom cover accommodating therein the array substrate and the encapsulating structure, and at least one heat dissipation pattern disposed between the encapsulating structure and the bottom cover. The heat dissipation pattern may include a porous framework layer and a heat emission layer composed of particles coated on the framework layer. This heat dissipation pattern may allow heat transfer from the encapsulating structure to the bottom cover to be performed more quickly and efficiently.

Abstract: The present disclosure relates to a display device including a piezoelectric film type actuator, the display device having a structure in which a groove is provided in a rear surface of a metal layer for supporting and encapsulate a rear surface of a display panel and the piezoelectric film type actuator is disposed in the groove. Accordingly, the display device may reduce the overall thickness and improve heat dissipation performance.
