Patent ID: 8421967

Claim:
A liquid crystal display device comprising: a reflection region for reflecting incident light toward a display surface, wherein, the reflection region includes a metal layer, an insulating layer formed on the metal layer, a semiconductor layer formed on the insulating layer, and a reflective layer formed on the semiconductor layer; a first recess and a second recess located inside the first recess are formed on a surface of the reflective layer in the reflection region; the metal layer has an aperture or a recess; the semiconductor layer has an aperture; one of the first recess and the second recess is formed according to the aperture or recess of the metal layer, and the other of the first recess and the second recess is formed according to the aperture of the semiconductor layer; wherein the metal layer has a composition which varies along a thickness direction of the metal layer; and wherein the metal layer is made of molybdenum nitride, and a nitrogen content in the molybdenum nitride of the metal layer decreases toward the insulating layer.
