Patent ID: 7952664

Claim:
A manufacturing method for a substrate of a reflective liquid crystal display device, comprising: forming gate and data lines on the substrate; forming a thin film transistor adjacent to where a gate line and a data line cross over each other, wherein the thin film transistor has a gate electrode, a source electrode and a drain electrode; forming a passivation layer over the thin film transistor; wherein the passivation layer has an uneven surface having curved profiles that are asymmetric; and forming an opaque conductive pixel electrode having a reflective surface with curved profiles that are asymmetric on the passivation layer, wherein forming a passivation layer comprises: forming a plurality of hemispheric bumps by patterning and melting an upper portion of the passivation layer; and rubbing the hemispheric bumps in one direction to obtain pushed-over curved profiles on the upper portion of the passivation layer.
