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.

Abstract: An array substrate and a display panel are provided. The array substrate includes a non-display area and a display area. The non-display area includes a first non-display area and a second non-display area, and the display area includes a normal display area and a wiring area. The normal display area is surrounded by the first non-display area, the wiring area is surrounded by the normal display area, and the second non-display area is surrounded by the wiring area. The second non-display area comprises an opening area. In the solution, since the number of data lead lines in the same layer in the wiring area is reduced, a line distance between adjacent data lead lines is increased, thereby reducing coupling capacitance between adjacent data lead lines arranged in the same layer.

A pixel includes at least three sub-pixels of different colors, a first color sub-pixel having a first color filter, a second color sub-pixel having a second color filter, and a third color sub-pixel having a third color filter. The non-rectangular shape display region includes at least one irregular edge intersecting the row direction and the column direction. The pixels intersecting the at least one irregular edge are first pixels and the remained pixels are second pixels. A first pixel is divided by the at least one irregular edge into a first light-transmitting region configured in the non-rectangular shape display region and a first light-shielding region shielded by a black matrix.
