Abstract

The invention provides a display panel and a manufacturing method thereof. The display panel comprises an array substrate and a color film substrate arranged corresponding to the array substrate. Thearray substrate comprises a substrate body, a source-drain electrode layer, an active layer, a grid electrode insulating layer, a grid electrode layer, a flat layer and a pixel electrode layer which are arranged in a stacked mode. According to the invention, an inverted thin film transistor structure is formed on the array substrate; the pixel electrode layer covers the wiring of the source-drainelectrode layer; therefore, the parasitic capacitance between the source-drain electrode layer on the array substrate and the common electrode layer on the color film substrate is blocked, and the parasitic capacitance between the source-drain electrode layer on the array substrate and the pixel electrode layer is blocked; signal crosstalk is avoided, and the display and touch quality of a productis improved.

Description

technical field [0001] The invention relates to the display field, in particular to a display panel and a manufacturing method thereof. Background technique [0002] The current products are developing towards high resolution, and the size of the display panel is getting smaller and smaller. Among them, the parasitic capacitance in the pixel circuit has a negative impact on the product quality, and the signal crosstalk becomes serious. [0003] Such as figure 1 As shown, it is a schematic structural diagram of a conventional display panel. The display panel 90 includes an array substrate 91 and a corresponding color filter substrate 92, wherein the array substrate 91 includes a substrate layer 911 and a plurality of thin film transistors are disposed on the substrate layer 911. Each thin film transistor includes a gate layer 912, a gate insulating layer 913, an active layer 914, a source-drain layer 915, a planar layer 916, and an anode layer 917 from bottom to top. The ca...
