Problems solved by technology

[0004] At present, the display industry is gradually developing towards higher definition, higher resolution, and thinner. Therefore, the number of pixels per inch (Pixels Per Inch, PPI) in the display panel design of many existing high-end products is getting higher and higher. The photoconductivity of the semiconductor layer on the active switch is relatively high, so there will be a large leakage current under light irradiation.

Abstract

The invention provides a display panel which comprises a substrate and an active switch arranged on the substrate. A shading layer is arranged between the active switch and the substrate and the active switch comprises a semiconductor layer. The shading layer covers the semiconductor layer completely. The shading layer can effectively reduce the illumination of backlight on the semiconductor layer, so that illumination light leak currents can be further reduced, the influence of light leak currents on image display can be effectively reduced and the display quality of the display panel can be further improved.

Description

technical field [0001] The present invention relates to the field of display technology, and more specifically, to a display panel 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 transis...
