Abstract:
1. A manufacturing method of a liquid crystal display device, comprising: forming a plurality of transistors, the formation of the plurality of transistors comprising: forming a first insulating layer over the source electrodes and the drain electrodes; forming contact holes by selectively removing first parts of the first insulating layer wherein the first parts overlap with the drain electrodes, and removing a second part of the first insulating layer, a third part of the semiconductor layer, and a fourth part of the gate insulating layer wherein each of the second part, the third part, and the fourth part overlaps with neither the source electrodes nor the drain electrodes, by a third photolithography step, wherein the third photolithography step comprises a step of exposing a part of the gate wiring positioned between the plurality of transistors to divide the semiconductor layer; forming pixel electrodes over the first insulating layer by a fourth photolithography step, wherein the fourth photolithography step is performed so that the pixel electrodes are electrically disconnected from the exposed gate wiring; and forming, over the exposed gate wiring, a second insulating layer serving as a spacer maintaining a space that is to be filled with a liquid crystal.
