Liquid crystal display device
First Claim
1. A liquid crystal display device comprising:
- a TN liquid crystal cell constituted by sandwiching a nematic liquid crystal which is aligned at a twist angle of about 90°
between a first and a second transparent substrate each having transparent electrodes;
an absorption-type polarizing film provided on the outside, which is the visible side of said TN liquid crystal cell, of said second substrate;
a reflection-type polarizing film provided on the outside, which is the opposite side to the visible side of said TN liquid crystal cell, of said first substrate;
a scattering layer provided on the outside of said reflection-type polarizing film; and
a mirror reflector provided on the outside of said scattering layer.

Abstract
A TN liquid crystal cell constituted by sandwiching a nematic liquid crystal which is aligned at a twist angle of about 90° between a first and a second transparent substrate each of which has transparent electrodes is used, an absorption-type polarizing film is provided on the outside, which is the visible side, of the second substrate, and a reflection-type polarizing film, a scattering layer, and a mirror reflector are provided in order on the outside, which is the opposite side to the visible side of the TN liquid crystal cell, of the first substrate, thereby constituting a liquid crystal display device for performing a reflection display of information of character and image in an achromatic metallic tone within a bright diffused white background.
