Abstract: A display device includes a first substrate, a second substrate, and a liquid crystal layer. The first substrate includes pixels, some of the pixels are disposed in a first area and some of the pixels are disposed in a second area. The second substrate is spaced apart from and coupled to the first substrate. The liquid crystal layer is disposed between the first substrate and the second substrate. Each pixel is associated with a viewing angle, an imaginary line extending from a center of the viewing angle, and an angle between a surface of the first substrate and the imaginary line. The angle of a pixel disposed in the first area differs from the angle of a pixel disposed in the second area.
