A reflectance-type liquid crystal display device includes a first light scattering unit on a first substrate, a reflecting layer having a second light scattering unit on a second substrate, and a liquid crystal layer between the two substrates. One of the two light scattering units defines a regular-directional scattering unit which can easily control the reflectance characteristics, and the other light scatterin unit defines a random-directional scattering unit which prevents the light interference caused by the regular-directional scattering unit.

Reflectance liquid crystal display having a limited interference effect

A reflective-type liquid crystal display device is disclosed which comprises first and second substrates; a metal layer having a convex-concave surface over the insulating layer; a &lgr;/4 phase retardation optical film over the second substrate. The convex portion of the metal has a long width in a first direction perpendicular to the main viewing angle direction of the user. Polarization direction of the polarizer is at 90&deg; with respect to the first direction, and slow axis of the optical film is at 45&deg; with respect to the polarization direction. This reflective-type LCD has a high reflective luminance in the main viewing angle direction. Further, because TE(transverse electric) polarized light is incident on the metal transverse electric, the reflective luminance is much more improved.
