ARRAY SUBSTRATE FOR LCD PANEL AND MANUFACTURING METHOD THEREOF

摘要

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.
