Abstract: An array substrate and a display panel are provided, which include a base and a plurality of semiconductor devices disposed on the base. An active defining portion is provided on the base, a junction of a connecting surface and a first top surface of the active defining portion is a first edge. The semiconductor device includes an active layer and a gate, one or more single crystal starting points of the active layer correspond to the first edge. An area where two rows of single crystal particles parallel to the first edge on both sides of the one or more single crystal starting points is a single crystal area, the channel portion of the active layer is disposed in the single crystal area, and the gate is provided with in a direction perpendicular to the base and covers only one row of the two rows of single crystal particles.

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.

Abstract: An array substrate, a display panel, and a display device are provided. The array substrate includes a base; a buffer layer and a thin film transistor. The buffer layer is provided on the base and includes a first buffer layer and a second buffer layer. The first buffer layer is disposed between the second buffer layer and the base. A refractive index of the first buffer layer is greater than a refractive index of the base and a refractive index of the second buffer layer. A ratio of the refractive index of the first buffer layer to the refractive index of the base is less than or equal to 1.25. The thin film transistor is provided on a side of the buffer layer away from the base.
