Patent ID: 7652734

Claim:
An array substrate of a reflective liquid crystal display device, comprising: gate and data lines on the substrate; a thin film transistor adjacent to where a gate line and a data line cross over each other to define a pixel region, the thin film transistor has a gate electrode, a source electrode, and a drain electrode; a passivation layer directly on the thin film transistor, the passivation layer formed with an uneven surface having a continuous series of convex curved profiles that are asymmetric and a flat surface, wherein at least some of the converge to form a point, the passivation layer including an organic material, wherein the uneven surface corresponds to the pixel region and the flat surface corresponds to the thin film transistor, and wherein the continuous series of convex curved profiles have substantially the same size as each other; and an opaque conductive pixel electrode formed directly on the passivation layer, the pixel electrode having a reflective surface with curved profiles that are asymmetric, wherein a radius of curvature for one side of each curved profile of the pixel electrode is larger than a radius of curvature of the other side of each curved profile of the pixel electrode.
