Abstract
A liquid crystal display device includes a reflection region for reflecting incident light toward a display surface, wherein, the reflection region includes a metal layer formed on a substrate, a semiconductor layer formed above the metal layer, and a reflective layer formed above the semiconductor layer; and the reflection region includes a first recess formed on a surface of the reflective layer, a second recess formed on the surface of the reflective layer in the first recess, and a third recess formed on the surface of the reflective layer in the second recess. The liquid crystal display device provides a low-cost transflective-type or reflection-type liquid crystal display device having a high image quality.
