Abstract
A display apparatus having a plurality of subpixels is provided. The display apparatus includes an array substrate and a counter substrate facing the array substrate. The counter substrate includes a base substrate; an optical compensation device on the base substrate configured to adjust light emitting brightness values of the plurality of subpixels to target brightness values respectively; and a plurality of light shielding walls on the base substrate. The optical compensation device include a plurality of photosensors configured to respectively detect light emitting brightness values of the plurality of subpixels. A respective one of the plurality of light shielding walls is configured to at least partially shield a lateral side of a respective one of the plurality of photosensors from light emitted from adjacent subpixels.
