Abstract:
1. A thin film transistor array panel for a liquid crystal display comprising an insulating substrate including a display area, a peripheral area at the circumference of the display area, and an outer area comprising other than the display area and the peripheral area; a black matrix formed on the display area of the insulating substrate and having an opening of a matrix array corresponding to pixels; a common wire formed with the same layer as the black matrix and including a common signal line for transmitting a common signal from external circuits; red, blue and green color filters formed at the pixels on the insulating substrate; an insulating layer covering the black matrix and the color filters; a gate wire including a gate line and a gate electrode connected to the gate line, and formed on the insulating layer; a gate insulating layer covering the gate wire on the insulating layer; a semiconductor pattern formed on the gate insulating layer; a data wire including a source electrode and a drain electrode that are made of a same layer on the semiconductor pattern and separated from each other, and a data line connected to the source electrode and defining a pixel in a matrix array by crossing the gate line; a passivation layer covering the data wire and having a first contact hole exposing the drain electrode; and a pixel wire including a pixel electrode connected to the drain electrode through the first contact hole.
