Abstract

An embodiment of the present application discloses an array substrate and a liquid crystal display panel. The array substrate uses a first barrier layer including a first aperture in an aperture region. The first barrier layer is at least correspondingly disposed in a thin film transistor disposing region and a gate driver on array circuit region. The first barrier layer is configured to block the alkaline cation from spreading along a direction to the active layer. Along a direction at a right angle from the substrate to the active layer, a depth by which the alkaline cation enters the first barrier layer is less than or equal to 20 Å.
