Problems solved by technology

[0004] In the top-gate self-aligned thin film transistor manufacturing process, the semiconductor layer needs to be conductorized. However, the semiconductor layer that has undergone the conductorization process will be significantly affected in the subsequent manufacturing process, affecting the conductorization effect of the semiconductor layer. Semiconducting layer does not work as expected

Abstract

The invention discloses an array substrate, and the array substrate comprises a substrate; a shading layer which is formed on the substrate; a buffering layer which is formed on the shading layer; a semiconductor layer which is formed on the buffering layer; a protection layer which is formed on the semiconductor layer; an insulating layer which is formed on the protection layer; and an interlayer dielectric layer which is formed on the protection layer. The substrate is also provided with a source electrode layer, a drain electrode layer and a grid electrode layer, wherein the source electrode layer and the drain electrode layer are formed on the interlayer dielectric layer, and are respectively connected to conductor parts at two ends of the semiconductor layer. The insulating layer is disposed between the grid electrode layer and the semiconductor layer, and the interlayer dielectric layer covers the grid electrode and the protection layer. The insulating layer covers the semiconductor layer, thereby effectively guaranteeing that a to-be-conducted semiconductor layer region is not exposed, and effectively reducing the impedance impact of the conductor parts of the semiconductor layers in a subsequent manufacturing process.

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. Background technique [0002] The display has many advantages such as thin body, power saving, no radiation, etc., and has been widely used. Most of the displays currently on the market are backlight displays, which include a display panel and a backlight module. The working principle of the display panel is to place liquid crystal molecules between two parallel substrates, and apply a driving voltage on the two substrates to control the rotation direction of the liquid crystal molecules, so as to refract light from the backlight module to generate images. [0003] Among them, Thin Film Transistor-Liquid Crystal Display (TFT-LCD) has gradually occupied a dominant position in the display field due to its low power consumption, excellent picture quality, and high production yield. Similarly, a thin film transistor di...
