Abstract
A display apparatus includes: a first substrate including a first sub-pixel region, a second sub-pixel region, and a white sub-pixel region; a first color filter disposed on the first substrate in the first sub-pixel region; a second color filter disposed on the first substrate in the second sub-pixel region; an organic layer disposed on the first substrate, the organic layer covering the first color filter, the second color filter, and the white sub-pixel region; a second substrate facing the first substrate; a liquid crystal layer disposed between the first substrate and the second substrate; and a compensation pattern disposed between the first substrate and the second substrate, the compensation pattern being further disposed in the white sub-pixel region. A height of the liquid crystal layer corresponding to the white sub-pixel region is smaller than heights of the liquid crystal layer corresponding to the first sub-pixel region and the second sub-pixel region.
