ABSTRACT:
A method for producing a light reflecting structure in a transflective or reflective liquid crystal display uses one or two masks for masking a photoresist layer in a back-side exposing process. The pattern on the masks is designed to produce rod-like structures or crevices and holes on exposed and developed photoresist layer. After the exposed photoresist is developed, a heat treatment process or a UV curing process is used to soften the photoresist layer so that the reshaped surface is more or less contiguous but uneven. A reflective coating is then deposited on the uneven surface. One or more intermediate layers can be made between the masks, between the lower mask and the substrate, and between the upper masks and the photoresist layers. The masks and the intermediate layers can be made in conjunction with the fabrication of the liquid crystal display panel.
