Abstract
A transflective-type and a reflection-type liquid crystal display device having a high reflection efficiency and a high image quality are provided. A liquid crystal display device of the present invention is a liquid crystal display device including a reflection region, wherein the reflection region includes an insulating layer, a semiconductor layer and a reflective layer formed on a metal layer having a plurality of recesses therein; a plurality of protrusions of the metal layer, each having a bottom surface, an upper surface and a slope, are formed between the plurality of recesses of the metal layer; and a width a of a bottom surface of at least one of the plurality of protrusions in the metal layer satisfies a≦2(x+y)/tan θ, where a denotes the width of the bottom surface of each of the plurality of protrusions, x a thickness between the bottom surface and the upper surface, θ a tilt angle of the slope with respect to the bottom surface, and y a total thickness of the insulating layer, the semiconductor layer and the reflective layer.
