Array substrate and liquid crystal display panel

Abstract

The invention provides an array substrate and a liquid crystal display panel. The array substrate comprises a baseplate substrate layer, a thin film transistor, a first passivation layer, a color resistance layer, a pixel electrode layer and a second passivation layer, wherein the thin film transistor is arranged on the baseplate substrate layer; the first passivation layer is arranged on the thinfilm transistor; the first passivation layer is provided with a first through hole; a drain region of the thin film transistor is exposed out through the first through hole; the color resistance layer is arranged on the first passivation layer and is used for forming a color filter; the color resistance layer is provided with a second through hole; a drain region of the thin film transistor is exposed out through the second through hole; the pixel electrode layer is arranged on the color resistance layer, is electrically connected with the drain region of the thin film transistor through thefirst through hole and the second through hole and is used for forming a pixel electrode; and the second passivation layer is arranged on the pixel electrode layer. The array substrate has the advantages that the connection of the pixel electrode layer and a second metal layer does not need to pass through the second passivation layer, so that the second passivation layer is free from hole digging, the protection capability for the color resistance of the whole second passivation layer is strong and the air bubble is prevented.

Description

technical field [0001] The invention relates to the field of liquid crystal displays, in particular to an array substrate and a liquid crystal display panel. Background technique [0002] With the development of technology, more and more liquid crystal display devices are used. In order to achieve a better color display of the liquid crystal display device, a layer of color film is added to the array substrate of the current liquid crystal display device, so that the three primary colors of RGB are realized on the array substrate, and the alignment between the array substrate and the color film substrate is avoided. operation, so that the liquid crystal display device can perform full-color display better. The above technology is called COA (Color Filter on Array) technology. [0003] see figure 1 The structure of the existing COA array substrate is as follows. The COA array substrate includes a substrate substrate layer 101; a first metal layer 102 is arranged on the sub...

Problems solved by technology

If the offset of the two holes is too large, the less overlapping end of the first passivation layer 106 and the second passivation layer 108 will not protect the color resistance well, and the bubbles in the color resistance will easily seep out, resulting in There are often bubbles at the opening (CFopen), which affects the use of the product
