Problems solved by technology

However, since the light-shielding layer usually only blocks the light that is vertically incident on the channel region of the active layer, the metal layers (such as the source-drain metal layer) of the thin film transistor and the stacked film layers with different refractive indices will reflect part of the light from the bottom backlight. , when the reflected light is incident on the channel re

Abstract

The invention discloses an array substrate, a display panel and a display apparatus. The array substrate comprises a substrate and a thin film transistor array positioned on the substrate, wherein a thin film transistor in the thin film transistor array comprises a source, a drain, a gate and an active layer; the active layer comprises a channel region which is controlled by the gate and formed between the source and the drain; the display panel comprises an optical barrier layer which is positioned on one side, far from the substrate, of the gate, and positioned on one side, far from the substrate, of the active layer; and the orthographic projection of the optical barrier layer towards the substrate covers that of the channel region towards the substrate. According to the scheme disclosed by the invention, the optical leakage current of the thin film transistor in the array substrate generated by illuminance on the active layer can be avoided, so that the display effect can be improved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to an array substrate, a display panel and a display device. Background technique [0002] With the continuous expansion of the application field of the display technology, the requirement for the display performance is getting higher and higher. Usually, a display panel is provided with many thin film transistors (Thin Film Transistor, TFT), including a thin film transistor array disposed in a display area, and a thin film transistor disposed in a driving circuit in a non-display area. Most of these thin film transistors use monocrystalline silicon or polycrystalline silicon as the active layer. Since the silicon in the active layer will generate photocarriers under the irradiation of light, the leakage current of the thin film transistor device will increase when it is turned off, which will affect the display. performance, so it is necessary to block the light that hi...
