Abstract

The invention provides an array substrate, a production method thereof, a display panel, and a display device, and relates to the display technology field. The array substrate comprises a substrate; an auxiliary shade layer, an insulation layer, a main shade layer, and a buffer layer, which are sequentially arranged in a direction away from the substrate. A plurality of grid lines and a plurality of data lines are used to form a plurality of pixel areas in a limited way, and thin film transistors are disposed in the pixel areas. The auxiliary shade layer comprises a plurality of first auxiliary shade parts, and the main shade layer comprises a plurality of main shade parts. The orthogonal projection of the channel areas of the active layers of the thin film transistors on the array substrate is disposed in the orthogonal projection of the main shade parts on the array substrate, and the orthogonal projection of the channel areas of the active layers of the thin film transistors on the array substrate is disposed in the orthogonal projection of the first auxiliary shade parts on the array substrate. By adopting the technical scheme provided by the invention, intensities of light irradiated on the channel areas of the active layers of the thin film transistors are reduced, and the light leakage flows of the thin film transistors are reduced.

Description

【Technical field】 [0001] The present invention relates to the field of display technology, in particular to an array substrate and a manufacturing method thereof, a display panel and a display device. 【Background technique】 [0002] Generally, a display device includes a display panel and a backlight module, wherein the display panel is used to display images, but the display panel itself cannot emit light, and the backlight module needs to provide light for it. [0003] The display panel includes an array substrate, a color filter substrate, and a liquid crystal layer located between the array substrate and the color filter substrate, wherein the array substrate is arranged facing the backlight module, and a plurality of thin film transistors are arranged on the array substrate, and the active layer of the thin film transistor The channel area is sensitive to light. In the prior art, a light-shielding layer is provided on the side of the active layer facing the backlight mo...
