DISPLAY APPARTUS AND DIFFUSER PLATE THEREOF

According to an embodiment of the present invention, the display device includes: a chassis; a light source module installed in the chassis and configured to emit light; a diffusion plate disposed in front of the light source module and configured to diffuse the light emitted from the light source module; and a liquid crystal panel disposed in front of the diffusion plate and configured to display an image. The diffusion plate includes a pattern layer including diffusion patterns protruding toward the light source module, and a reflective layer provided in contact with the pattern layer such that a portion of light traveling through the pattern layer is totally reflected at a boundary surface between the reflective layer and the pattern layer. According to the present invention, it is possible to secure a slim design of the display device and uniformity of luminance at the front of the display panel at the same time. 본 발명의 실시예에 따르면 디스플레이 장치는 섀시와, 섀시에 설치되고 광을 발산하는 광원 모듈과, 광원 모듈에서 발산된 광을 확산하도록 광원 모듈의 전방에 배치되는 확산판과, 확산판의 전방에 배치되고 화상을 표시하는 액정 패널을 갖는다. 확산판은 광원 모듈을 향해 볼록한 확산 패턴들을 갖는 패턴층과, 패턴층에서 진행하는 광의 일부가 패턴층과의 경계면에서 전반사되도록 패턴층에 접하도록 형성되는 반사층을 갖는다.
