Patent ID: 7884909

Claim:
A method of fabricating a substrate for a transflective liquid crystal display device, comprising: forming a plurality of gate lines on a substrate; forming at least one data line, a thin film transistor including a semiconductor layer of silicon, a source electrode and a drain electrode, the at least one data line crossing the plurality of gate lines to define a pixel region including a transmissive portion and a reflective portion, the source and drain electrodes directly contacting an upper surface of the semiconductor layer, the source electrode being connected to the at least one data line, and the drain electrode being spaced apart from the source electrode; forming a first insulating layer directly covering a portion of the thin film transistor, the first insulating layer uncovering the pixel region and a portion of the drain electrode; forming a transparent material layer over the entire surface of the substrate including a first photoresist pattern and the first insulating layer, wherein the first photoresist pattern contacts all top surfaces of the first insulating layer; simultaneously removing the first photoresist pattern and a portion of the transparent material layer formed on the first photoresist pattern by lifting off the first photoresist pattern to form a transparent electrode in the pixel region, the transparent electrode directly contacting the drain electrode and the semiconductor layer and covering an entire surface of the transmissive and reflective portions; forming a second insulating layer on the transparent electrode, the second insulating layer having a first uneven surface; and forming a reflective layer in the reflective portion, the reflective layer having a second uneven surface corresponding to the first uneven surface, wherein the reflective layer overlaps the transparent electrode in the reflective portion with the second insulating layer therebetween.
