Abstract: A display apparatus includes a display panel receiving light from a light source. The display panel includes a liquid crystal panel, first and second polarizers respectively disposed on front and rear sides of the liquid crystal panel, and an optical layer disposed on a front surface of the second polarizer. The optical layer includes a first resin layer having light absorption portions for absorbing a portion of incident light, a second resin layer disposed on a front surface of the first resin layer, the second resin layer having a higher refractive index than the first resin layer, the second resin layer having light diffusion portions for diffusing light not absorbed by the light absorption portions.
