Patent ID: 8284356

Claim:
A photomask used for forming a convex-concave surface on a reflective area of liquid crystal display (LCD) device including comb teeth electrodes for driving liquid crystal (LC) molecules in a lateral-electric-field drive mode, the reflective area in at least a part of a pixel, wherein said photomask comprises: a first area corresponding to, in said reflective area, an area under each of said comb teeth electrodes, and a second area corresponding to, in said reflective area, and area between adjacent electrodes of said comb teeth electrodes, said second area being present between adjacent portions of said first area, wherein said second area has a predetermined pattern formed by at least one light transmitting area and at least on light absorbing area absorbing more light than said at least one light transmitting area, and said first area has a uniform light transmitting property is used for forming said convex-concave surface on said reflection film, and has no convex-concave pattern in an area overlapping said electrodes, wherein said first area comprises a half-tone mask.
