Abstract

The invention discloses an array substrate, a display panel and a preparation method of the array substrate. The array substrate comprises: a substrate body and a film transistor layer, wherein the film transistor layer is arranged on the substrate body, and comprises an active layer; and a shielding layer, wherein the shielding layer is arranged between the substrate body and the film transistor layer, a groove is formed in the shielding layer, and at least part of the active layer extends into the groove. Through the mode, the problem of current leakage caused by illumination of the active layer is improved, and the working stability of the film transistor is improved.

Description

technical field [0001] The present application relates to the field of display technology, and in particular to an array substrate, a display panel and a method for preparing the array substrate. Background technique [0002] Currently, a liquid crystal display panel (Liquid Crystal Display, LCD) and an organic light emitting diode display panel (Organic Light Emitting Diode, OLED) both have an array substrate, and a thin film transistor (Thin Film Transistor, TFT) is disposed on the array substrate. [0003] In thin film transistors, the active layer is a very important film layer, which determines the performance of thin film transistors to a large extent, and many active layers have the problem of leakage current when exposed to light, which will lead to the failure of thin film transistors. Instable performance; in order to solve this technical problem in the prior art, a shielding layer is provided under the active layer, but the effect of the shielding layer is limited...
