Abstract
A transflective liquid crystal display and method of fabricating the same. The pixel region of the transflective comprises a thin film transistor, a transmissive electrode, and a reflective electrode, wherein the overlap of the reflective electrode and the transparent electrode composes a reflective region and the non-overlapping region of the reflective electrode and the transparent electrode form a transmissive region, and the transparent electrode and the source and the drain regions of the thin film transistor are formed of the same silicon layer.

16. A method for fabricating a transflective liquid crystal display, comprising steps of:
-
providing a substrate, comprising a plurality of pixels with a transmissive region and a reflective region;
forming a silicon layer on the pixels;
forming a first insulating layer on the substrate covering the silicon layer;
forming a first conductive layer on the first insulating layer, and defining the first conductive layer into at least two scan lines and a gate electrode;
forming a doped silicon layer by the side of the gate electrode, wherein the doped silicon at one side of the gate electrode serves as a drain region, the doped silicon at the other side of the gate electrode serves as a source region, and the doped silicon covering a large portion of the pixels serves as a transparent electrode;
forming a second insulating layer on the first insulating layer covering the gate electrode;
forming a first contact plug, perforating through the second insulating layer and the first insulating layer to the source and drain region;
forming a second conductive layer on the second insulating layer, and defining the second conductive layer into at least two data lines, a drain electrode, and a source electrode, wherein the data lines and the scan lines intersect and form a pixel region;
forming a passivation insulating layer on the second insulating layer covering the data lines, the drain electrode, and the source electrode;
removing a portion of the passivation insulating layer, the second insulating layer, and the first insulating layer exposing the transparent electrode; and
forming a reflective electrode on the passivation insulating layer, wherein the reflective electrode is located within the reflective region. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23)
