LIQUID CRYSTAL DISPLAY DEVICE
First Claim
1. A liquid crystal display device having a plurality of pixels, and comprising, in each of the plurality of pixels, a reflection region for reflecting incident light toward a display surface, wherein,the reflection region includes a metal layer, a semiconductor layer formed on the metal layer, and a reflective layer formed on the semiconductor layer;
- a plurality of first recesses or protrusions and a plurality of second recesses or protrusions are formed on a surface of the reflective layer;
the plurality of first recesses or protrusions are formed so as to conform to the shapes of recesses or protrusions of the metal layer, and the plurality of second recesses or protrusions are formed so as to conform to the shapes of recesses or protrusions of the semiconductor layer; and
the plurality of first recesses or protrusions have a plurality of first pairs of first recesses or protrusions adjoining along a first direction, the plurality of first pairs including two pairs whose intervals between recesses or protrusions are different from each other, orthe plurality of second recesses or protrusions have a plurality of second pairs of second recesses or protrusions adjoining along a second direction, the plurality of second pairs including two pairs whose intervals between recesses or protrusions are different from each other.

Abstract
Reflection-type and transflective-type liquid crystal display devices having a high image quality, in which moiré or coloration is reduced, are provided at low cost.
A liquid crystal display device according to the present invention is a liquid crystal display device having a reflection region in each of a plurality of pixels; the reflection region includes a metal layer, a semiconductor layer, and a reflective layer; a plurality of recesses and protrusions are formed on the surface of the reflective layer; the plurality of recesses are formed according to apertures in the metal layer; the plurality of protrusions are formed so as to conform to the shape of the semiconductor layer; a plurality of pairs among the plurality of recesses that adjoin along a direction include two pairs whose intervals between recesses are different from each other; and a plurality of pairs among the plurality of protrusions that adjoin along a direction include two pairs whose intervals between protrusions are different from each other.
