LIQUID CRYSTAL DISPLAY ELEMENT OR DISPLAY DEVICE USING THE SAME

摘要

PROBLEM TO BE SOLVED: To realize a liquid crystal display element provided with high speed responsiveness, further with high contrast and a display device using the same. SOLUTION: The display device utilizes a reflective liquid crystal light valve and is characterized by making retardation of an optical retardation plate arranged between such a polarizing element as for example a polarization beam splitter and the reflective liquid crystal light valve be roughly one quarter of a wavelength of incident light and further by arranging an optical axis (a phase lapping axis or a phase advancing axis) of the optical retardation plate and the polarization direction of the incident polarized light so as to be deviated from the each other with a little large angle than 0 deg..
