Abstract

The invention provides a manufacturing method of an array substrate. The method includes the steps that a first light-transmitting conducting film is formed on an underlayer base material; a light-transmitting passivation film is formed on the first light-transmitting conducting film at the temperature of not more than 200 DEG C; a second light-transmitting conducting film is formed on the light-transmitting passivation film. The invention further provides a manufacturing method of the light-transmitting passivation film and a manufacturing method of a liquid crystal display panel. Granular protrusions generated on the surface of the passivation layer can be reduced, and the penetration rate of the liquid crystal display panel can be increased.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to an array substrate, a light-transmitting passivation film and a method for manufacturing a liquid crystal display panel. Background technique [0002] For liquid crystal display panels such as FFS (Fringe Field Switching, fringe field switching technology) mode, three layers of thin films are formed on the substrate of the array substrate (ie, Array substrate), which are the common electrode layer, passivation layer, and pixel electrode layer. Currently, the industry generally uses a high temperature sputtering method exceeding 285° C. to form the passivation layer. However, in the process of high-temperature sputtering, the particle activity of the passivation material used to form the passivation layer is relatively high, resulting in more granular protrusions on the surface of the final passivation layer, which seriously affects the liquid crystal display panel....
