Abstract:
1. A thin film transistor substrate comprising; data wiring comprising a data line formed on an insulating substrate; red, green, and blue color filters formed on the insulating substrate; a buffer layer that is a low dielectric insulating film, the buffer layer being formed on the data wiring and the color filters, and having first contact openings for exposing predetermined parts of the data wiring; gate wiring formed on the buffer layer and comprising a gate line intersecting the data line to define pixels and a gate electrode connected with the gate line; a gate insulating film formed on the gate wiring and having second contact openings for exposing at least a part of the first contact openings; a semiconductor layer formed on areas of the gate insulating film that is formed on the gate electrode; and pixel wiring comprising a source electrode that is connected with the data line through the first and second contact openings, at least a part of which is in contact with the semiconductor layer, a drain electrode formed opposing the source electrode on the semiconductor layer, and a pixel electrode connected with the drain electrode.
