Abstract

The invention discloses a display panel and a manufacturing method thereof. The display panel comprises a first substrate; a metal layer arranged on the first substrate, wherein the metal layer comprises an electric contact region for electrically connecting with a corresponding conductive component; and a protective layer covered on the metal layer and avoiding the electric contact region, wherein the protective layer is located on the metal layer, the metal layer can be effectively prevented from corroding due to the protection of the protective layer with a certain thickness when performingthe anode etching, so that the corrosion on the circuit is reduced, and the circuit break caused by short-circuit due to large resistance is avoided.

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] 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 (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] The structure of the combination of electrode layer (ITO) and silver (Ag) is commonly used for the anode, metal aluminum (Al) is commonly used for the signa...
