TRANSMISSION TYPE SCREEN, IMAGE DISPLAY METHOD FOR TRANSMISSION TYPE SCREEN, AND PROJECTION DISPLAY APPARATUS

The transmission type screen includes: a Fresnel lens screen (20); and an image display element (30), in which the Fresnel lens screen includes: a Fresnel optical element (21) including a prism formed on an incident surface side as seen from the emitter; and a first light diffusion unit (22) for diffusing an image light passing through the Fresnel optical element, and the image display element includes: a lens element (40) for spatially dividing the image light from the Fresnel lens screen and changing a direction of the image light; a birefringent layer (90) provided at a subsequent stage of the lens element, for mixing image light obtained by spatial division; and a second light diffusion unit (60) provided at a subsequent stage of the birefringent layer, for diffusing the image light passing through the birefringent layer.
