Abstract
A compact, light projection type image display apparatus based on reflection image display devices which provide high brightness without contrast deterioration caused by light leakage associated with black image display. The apparatus uses, as polarizers/analyzers for reflection image display devices, reflection polarizing plates which function as polarizing plates by their grating function only in a specific direction. In each light path, the reflection polarizing plate is located just before/after the reflection image display device.
