Abstract

The invention provides an array substrate, a preparation method thereof and a display panel. The array substrate comprises a substrate base plate, a thin film transistor arranged on one side of the substrate base plate, a data line arranged on one side of the substrate base plate, and a connecting electrode making a source and a drain of the thin film transistor electrically connected with the data line, wherein the orthographic projection of an active layer of the thin film transistor on the substrate base plate is located in the orthographic projection of a grid of the thin film transistor on the substrate base plate. The projection of the active layer of the array substrate on a grid insulation layer is located in the projection of the grid on the grid insulation layer, the source and the drain are connected with the data line through the connecting electrode, and therefore the light electric leakage problem caused when the active layer is exposed out of the grid is reduced, and the display stability of the display panel formed by the array substrate is improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular, the present invention relates to an array substrate, a preparation method thereof, and a display panel. Background technique [0002] In the current pixel design, in order to save costs, the scheme of reducing the number of masks (MASK) is generally adopted, that is, the source-drain electrode layer (SD) and the active layer (ACT) share a half-tone mask (HTM MASK) scheme, and this scheme has been used on many pixel designs. However, there will be ACT under the SD metal formed by HTM NASK, refer to Figure 1a ~ Figure 1d and figure 2 ,especially in figure 2 In the three channels shown (I, II, III), the active layer (Active) at the source and drain electrodes will leak out of the gate (gate). When illuminated (hv), refer to figure 2 , the characteristics of the active layer 400 outside the gate 200 will change, the holes at the source 500 will increase with the light,...
