ABSTRACT:
A manufacturing method for an in-plane switching mode liquid crystal display (LCD) unit is provided. The method includes steps of: providing a substrate, forming a first conductive layer on the substrate, patterning the first conductive layer to form a gate line, a comb-shaped first electrode, a wiring pad, and a comb-shaped second electrode by a first photo etching process, forming a first insulation layer and a first semi-conductive layer, patterning the first insulation layer and the first semi-conductive layer to form a channel, an insulation structure, a dielectric layer, and plural crossed-conductive line insulation structures by a second photo etching process, forming a second semi-conductive layer and a second conductive layer on the substrate, patterning the second semi-conductive layer and the second conductive layer to form a source/drain electrode, a data line, a connecting electrode, and a first electrode by a third photo etching process, and forming a passivation layer.
