Abstract
A display apparatus includes an active device array substrate, an opposite substrate disposed opposite to the active device array substrate, and a display medium disposed between the active device array substrate and the opposite substrate. The opposite substrate includes a first base and a light-shielding structure disposed on the first base and located between the first base and the active device array substrate. The light-shielding structure has a first dielectric layer, a second dielectric layer, a third dielectric layer, a metal layer, a fourth dielectric layer, a fifth dielectric layer, and a sixth dielectric layer stacked sequentially in a direction from the first base to the active device array substrate. The first, second, and third dielectric layers have different thicknesses. The fourth, fifth, and sixth dielectric layers have different thicknesses.
