Abstract
An array substrate includes a first substrate and a planarization layer disposed on a side of the first substrate. The planarization layer is provided with a first through hole. A cross-sectional area of the first through hole gradually decreases in a direction from the planarization layer toward the first substrate. An angle between a sidewall of the first through hole and a bottom surface of the first through hole is 50° to 90°.
