Abstract

See full text

An array substrate includes a base substrate, a light-shielding pattern, a buffer pattern, an active layer, a gate insulating layer and a first passivation layer provided with a first via, a second via and a third via, and a source and a drain. An entire orthographic projection of the active layer on the base substrate coincides with an orthographic projection of at least part of the buffer pattern on the base substrate. The orthographic projection of the buffer pattern on the base substrate is within a border of an orthographic projection of the light-shielding pattern on the base substrate, and its area is less than an area of the orthographic projection of the light-shielding pattern on the base substrate. One of the source and the drain is coupled to the active layer through the first via, and another one is coupled to the active layer through the second via and the light-shielding pattern through the third via.
