ABSTRACT:
In a liquid crystal display device of an IPS system, to realize reduction of manufacturing cost and improvement of yield by decreasing the number of steps for manufacturing a TFT.The present invention adopts a channel etch type bottom gate TFT structure, and is characterized in that patterning of a source region119and a drain region120and patterning of a source wiring121and a pixel electrode122are carried out by the same photomask.
