Abstract

PURPOSE: To lower the dependency of a contrast on visual fields and the degree of polarization of a display and to improve visibility by providing a diffuser in contact with outer side of an exit light side polarizer.
CONSTITUTION: The diffuser 6 is provided in contact with the outer side of the exit light side polarizer 5 of the liquid crystal display element with transmission illumination disposed with the liquid crystal 3 of the optically rotatory power changing with light by a voltage between a pair of the polarizers 2 and 5. The transmission illumination light is projected through the polarizer 2, the liquid crystal 3 and the polarizer 5 to the diffuser 6. The diffuser 6 acts to scatter the polarized light from the exit side polarizer 5 to the light approximate nearly to natural light and to lessen the dependency on visual field angles by isotropic scattering. Thus, the dependency of the contrast on the visual field angles and the degree of polarization of the display are lowered and, therefore, the visibility is improved.
