Document Type and Number:
Japanese Patent JP4834934
Kind Code:
B2
Abstract:
A color synthesizing optical apparatus comprises a plurality of reflection type light valves, a color synthesizing/analyzing optical system, and quarter wave plates disposed corresponding to the plurality of light valves. In a state to effect image-displaying, in one of first and second light valve groups, phase advance axes of the quarter wave plates are disposed substantially in parallel to predetermined axes within surfaces of the light valves which axes correspond to the respective predetermined axes within the projection image field plane of the light valves. In the other group in the same state, phase advance axes of the quarter wave plates are disposed substantially perpendicularly to the predetermined axes within the surfaces of the light valves which axes correspond to the respective predetermined axes within the projection image field plane of the light valves.
