A manufacturing method for a substrate for an LCD panel includes providing a substrate, and applying photoresist techniques to form a first wiring layer on the substrate and patterning the first wiring layer to form a first laminating layer. An insulating layer and a semiconductor film are also formed and the semiconductor film is patterned to form a second laminating layer. A second wiring layer is formed and patterned to create a third laminating layer, a passivation layer, and a conductive film, and the conductive film is patterned to form a pixel electrode and a fourth laminating layer. The first, second, third, and fourth laminating layers stack together to form the necessary spacer. A color filter substrate with a constant gap is held between the insulating layer and the first laminating layer, and between the passivation layer and the third laminating layer.
Description
technical field [0001] The invention relates to an array substrate applied to a liquid crystal display panel and a manufacturing method thereof. Background technique [0002] The liquid crystal display panel mainly includes a color filter substrate and an array substrate disposed opposite to each other, and a liquid crystal layer sandwiched between the two substrates. At the same time, the two substrates are separated by a spacer, and the spacer is used to keep the distance between the two substrates constant, so as to ensure uniform thickness of the liquid crystal display panel. [0003] At present, a manufacturing method of spacers is to coat photosensitive material on an array substrate and then fabricate columnar photosensitive spacers by exposure and development. When the liquid crystal display panel is assembled, the above two substrates are pasted together with a frame glue, and the photosensitive spacer is used to ensure a constant distance between the two substrate...
