THIN FILM TRANSISTOR ARRAY SUBSTRATE AND METHOD FOR FABRICATING THE SAME

摘要

PURPOSE: A thin film transistor array substrate and method for fabricating the same is provided to improve a pixel transparent rate while reducing a common electrode and a pixel electrode. CONSTITUTION: A gate line and a data line define a pixel area on a substrate(100). A switching device is arranged in the cross area of the data line and gate line. A pixel electrode(129) is located in the pixel area which is parallel direction with the data line. The common electrode and common line are formed on the upper part of the data line between a protective film(119) and an organic insulating film(250). The thickness of the organic insulating film on the pixel electrode is smaller than the thickness of the organic insulating film of data line area.
