ABSTRACT:
A thin film transistor substrate of horizontal electric field type liquid crystal display device includes: a gate line and a common line arranged in parallel on a substrate and formed from a first conductive layer; a data line formed from a second conductive layer, the data line crossing the gate line and the common line having a gate insulating film therebetween such that the data line, the gate line and the common line define a pixel area; a thin film transistor having a gate connected to the gate line and a source electrode connected to the data line; a common electrode extending from the common line into the pixel area and formed from the first conductive layer; a protective film for covering a plurality of signal lines and electrodes and the thin film transistor; a pixel hole in the protective film having an elongated shape that parallels the common electrode; and a pixel electrode connected to a side surface of a drain electrode of the thin film transistor and formed from a third conductive layer within the pixel hole.
