Array substrate and manufacturing method thereof

摘要

An array substrate of an LCD includes a substrate, a first wiring layer, a semiconductor film, an insulating layer, a second wiring layer, a passivation layer, a conductive film, and a spacer. The first wiring layer is patterned to a gate line, a gate electrode, and a first laminating layer. The semiconductor film is patterned to a channel layer and a second laminating layer. The second wiring layer is patterned to a source line, a source electrode, a drain electrode, and a third laminating layer. The conductive film is patterned to a pixel electrode and a fourth laminating layer. The spacer is a laminating structure at least includes the first, second, third, fourth laminating layers. A portion of insulating layer overlaps with the first laminating layer, and a portion of passivation layer overlaps with the third laminating layer.
