Abstract
Nematic liquid crystal display is provided with front side polarizer (13) and homeotropic orientation in the non-field state. The nematic liquid crystal (6) has a negative dielectric anisotropy. The display cell has an internal reflector (11) consisting of an insulating oxide layer with built-in aluminum flakes and a front side polarizer (8, 13). This display provides a reflection display with no back lighting.
