Abstract:
1. A method of fabricating a liquid crystal display device, comprising: forming a switching element on a substrate, the switching element comprising a gate electrode, a semiconductor layer, a source electrode, and a drain electrode; forming a first insulating layer on the substrate including the switching element; forming a plurality of photoresist patterns on the first insulating layer, wherein the plurality of photoresist patterns are spaced apart from each other; etching the first insulating layer and the plurality of photoresist patterns to form a plurality of concave portions directly adjacent to each other by using the photoresist patterns as masks, wherein the plurality of photoresist patterns are removed in the etching, whereby each concave portion has an entirely smoothly curved top surface in cross-section, and a portion, where the concave portions directly adjacent to each other of the first insulating layer meet each other, has a upwardly sharp point in cross-section, and the upwardly sharp point corresponds to each center of the plurality of photoresist patterns in cross-section; and forming a reflector on the first insulating layer and having a plurality of concave portions directly adjacent to each other, each of which has an entirely smoothly curved top surface in cross-section, due to the plurality of concave portions of the first insulating layer, whereby a portion, where the concave portions directly adjacent to each other of the reflector meet each other, has a upwardly sharp point in cross-section, wherein each of a portion of the first insulating layer and a portion of the reflector, which are over the switching element, has a flat top surface.
