Display panel and making process thereof, and display device

Abstract

The invention discloses a display panel and a making process thereof, and a display device; the display panel comprises a substrate and an electrode layer arranged on the substrate; the electrode layer is provided with a first defect position and an electrode repair layer; the transparent conductive repair layer covers on the first defect position. The transparent conductive repair layer can directly repair the first defect position on the electrode layer, thus allowing the electrode layer to restore normal works, solving the orientation adverse problems, providing better display quality, improving repair success rate, and preventing discard problems caused by overlarge defects.

Description

technical field [0001] The present invention relates to the field of display technology, and more specifically, to a display panel, its manufacturing process and a display device. Background technique [0002] Liquid crystal displays have many advantages such as thin body, power saving, and no radiation, and have been widely used. Most of the liquid crystal displays currently on the market are backlight liquid crystal displays, which include a liquid crystal panel and a backlight module. The working principle of the liquid crystal panel is to place liquid crystal molecules between two parallel glass substrates, and apply a driving voltage on the two glass substrates to control the rotation direction of the liquid crystal molecules, so as to refract the light from the backlight module to produce a picture. [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...

Problems solved by technology

[0004] However, after setting up the photo spacer (PS), it usually needs to be repaired. For example, if there is foreign matter attached, due to the poor adhesion between the foreign matter and the substrate, it is easy to cause partial peeling of the electrode layer due to the removal of the foreign matter when removing the foreign matter. Defects, or other defects that cause part of the electrode layer to peel off, so that the liquid crystal near the defect area will not operate normally during operation, the color filter substrate and or array substrate have no Vcom potential, and the potential appears Floating, resulting in there will be Problems with misalignment, such as anomalous casts of black, thus displaying reduced taste
