Abstract
The present disclosure provides an array substrate, a display panel, and a display device. The array substrate includes a base substrate; a first light-shielding layer, disposed on a side of the base substrate; a light-sensitive structure, disposed on the side of the first light-shielding layer away from the base substrate; a second light-shielding layer, disposed on the side of the light-sensitive structure facing away from the base substrate; and a light-shielding structure, disposed between the first light-shielding layer and the second light-shielding layer. The orthogonal projection of the light-shielding structure surrounds the orthogonal projection of the light-sensitive structure. In the direction perpendicular to the base substrate, the light-shielding structure includes a first light-shielding section and a second light-shielding section. The first light-shielding section is disposed close to the first light-shielding layer, and the first light-shielding section and the second light-shielding section are formed by different fabrication processes.
