Abstract:
1. A reflector for a reflection-type LCD device, comprising: plural interconnected protrusions each having a first height and having depressed areas between adjoining ones of the plural protrusions, each of the depressed areas having a second height less than said first height and having a closed geometric shape, as seen in plan view, said closed geometric shape being defined by a plurality of virtual lines formed at a third height between said first and second heights, each of said depressed areas being isolated from others of said depressed areas; a first bumpy layer covering the protrusions having a bumpiness generated by the protrusions; and a base layer of a reflector on the first layer, wherein the base layer has a bumpiness corresponding to the bumpiness of the first layer, thereby forming a protrusion pattern of a surface of the reflector, the protrusion pattern giving an inclination angle to the surface according to a specific distribution, and wherein each of the protrusions has a width W and a height D, where the width W and the height D have a relationship of 0.5≦(D/W)≦1.0.
