Abstract
A display apparatus includes pixel areas and a light blocking area between the pixel areas. The display apparatus includes a first base substrate, a thin film transistor, and first, second, and third color filters. The first color filter has a first color, the second color filter has a second color different from the first color, and the third color filter has a third color different from the first and second colors. In the light blocking area, the thin film transistor, the first color filter, and the third color filter at least partially overlap each other. The second color filter in at least one pixel area is connected to an adjacent second color filter disposed in an adjacent pixel area by a bridge portion, and the bridge portion is formed of the same material as the second color filter and is disposed in the light blocking area.
