Abstract:
A liquid crystal display (LCD) includes 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 includes an array of a plurality of reflecting surfaces which are formed so that at least a portion toward the front substrate of a side of the rear substrate is not parallel to the front substrate, a first medium layer having a first index of refraction and formed to have a flat surface on the reflecting surfaces, a second medium layer having a second index of refraction that is smaller than the first medium layer, and a third medium layer having a third index of refraction that is larger than the second medium layer, 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.
