    摘要： A display apparatus includes a chassis, a light source provided on the chassis and configured to emit light; a diffuser plate disposed in front of the light source and configured to diffuse the light emitted from the light source, and a liquid crystal panel disposed in front of the diffuser plate and configured to displaying an image. The diffuser plate includes a pattern layer including diffusion patterns protruding toward the light source, and a reflective layer provided in contact with the pattern layer such that portion of light traveling through the pattern layer is totally reflected at a boundary surface between the reflective layer and the pattern layer.
