Abstract

An array substrate, used for a display panel. The array substrate comprises a substrate; a gate layer that is provided on the substrate and comprises a gate line; an organic photoresist layer that is coated on the gate layer and the substrate and provided with a groove corresponding to the gate line; a gate insulation layer provided on the organic photoresist layer; a metal oxide layer provided on the gate insulation layer; and a metal layer provided on the metal oxide layer, wherein the metal layer and the metal oxide layer define source and drain region circuits, a semiconductor region, and a pixel region by means of lithography and etching processes.

Description

【Technical field】 [0001] The present invention relates to the field of display technology, in particular to an array substrate for a display panel and a manufacturing method thereof. 【Background technique】 [0002] Liquid crystal display (LCD) and organic light emitting diode display (organic light emitting diode, OLED) are currently the most widely used display products in the market. Their production technology is very mature, the product yield rate is high, and the production cost is relatively low. High market acceptance. The thin film transistor (thin film transistor) display panel manufacturing industry has been developed for many years, and the production process of the product has been very refined and mature. [0003] As the resolution of LCD and OLED becomes higher and higher, the proportion of thin film transistors per unit area is also increasing. Also because the gate and the source of the TFT and between the gate and the drain partially overlap, the parasitic...
