Patent ID: 7659953

Claim:
An LCD (liquid crystal display) comprising: a rear substrate and a front substrate; an LC (liquid crystal) layer placed between the rear substrate and the front substrate; and a reflecting region which reflects external light in at least a portion of a region toward the LC layer at a side of the rear substrate to illuminate the LC layer; and the reflecting region comprises: a first medium layer having a first index of refraction and formed to have a flat surface; a second medium layer having a second index of refraction that is smaller than the first medium layer; a third medium layer having a third index of refraction that is larger than the second medium layer; and an array of a plurality of reflecting surfaces that is formed on a surface of the first medium layer that faces the rear substrate, wherein at least a portion of the plurality of reflecting surfaces are not parallel to the front substrate, and a portion of light that travels from the rear substrate at an interface between the first medium layer and the second medium layer is totally internally reflected.
