PROJECTION VIDEO DISPLAY DEVICE AND PHASE DIFFERENCE PLATE

摘要

Provided is a projection video display device with which it is possible to alleviate crosstalk arising between a left-eye viewpoint image and a right-eye viewpoint image. A projection video display device comprises a liquid-crystal element which switches a polarized light of light which is emitted from a DMD between a first polarized light and a second polarized light, and a phase difference plate which is disposed on a projection face side with respect to the liquid-crystal element. The phase difference plate further comprises either a fast axis or a slow axis which differs for each of a plurality of areas.
