Patent ID: 8293549

Claim:
A method of fabricating a reflective pixel array substrate, comprising: providing a substrate having at least a pixel region, the pixel region having a reflective region and an element region; forming a first conductive layer on the substrate; patterning the first conductive layer to form a gate line, a gate electrode and a common line within the element region, and forming a plurality of protruding bumps which are polygonal or oval-shaped within the reflective region; forming a first insulating layer covering the substrate, the gate line, the gate electrode, the common line and the protruding bumps; forming a semiconductive layer on the gate electrode; forming a second conductive layer on the first insulating layer and the semiconductive layer; patterning the second conductive layer to form a source line, a source electrode, and a drain electrode within the element region, and to form a reflective electrode extending from the element region to the reflective region, the reflective electrode overlapping with the protruding bumps; forming a second insulating layer to cover the element region and the reflective region; and patterning the second insulating layer within the reflective region to form a plurality of first openings, wherein the reflective electrode disposed directly above each of the plurality of the protruding bumps is exposed through the first openings and the reflective electrode connects to the drain electrode electrically.
