Abstract: There is provided a display apparatus with an improved viewing angle. The display apparatus includes a display panel configured to receive light from a light source module, wherein the display panel includes: a liquid crystal panel; a first polarizing plate positioned on a rear side of the liquid crystal panel and a second polarizing plate positioned on a front side of the liquid crystal panel; and an optical layer positioned on a front surface of the second polarizing plate, wherein the optical layer includes: a resin layer having a first refractive index, and including an accommodating groove in which a light adjusting portion is disposed, the resin layer further including a light refractive pattern protruding toward a rear direction of the display panel; and an adhesive layer having a second refractive index different from the first refractive index, and bonding the resin layer with the second polarizing plate.
