An image display apparatus according to an embodiment of the present technology includes a light source section, one or more reflection type light modulators, an optical system, and a light shielding plate. The light source section includes at least one or more laser light sources. The one or more reflection type light modulators modulate and reflect incident light. The optical system splits light from the light source section into a plurality of split light beams, superimposes the plurality of split light beams on the one or more reflection type light modulators, and causes them to enter. The light shielding plate is provided in the optical system and includes an aperture provided on a path of each of the plurality of split light beams and a light shielding portion that shields reflection light from the reflection type light modulator to the light source section.

Image display apparatus and image display method

Provided is an image projection apparatus including: one or more light sources; one or more illumination optical systems; a first reflection-type light valve group including three light valves and being configured to modulate incident light based on first image information; a second reflection-type light valve group including three light valves and being configured to modulate incident light based on second image information; a first prism-type photosynthesizing member having a function of synthesizing, on one optical axis, light that is reflected by the first reflection-type light valve group; a second prism-type photosynthesizing member having a function of synthesizing, on one optical axis, light that is reflected by the second reflection-type light valve group; and a prism-type beam splitter configured to synthesize, on one optical axis, light that has been reflected by the first reflection-type light valve group and light that has been reflected by the second reflection-type light valve group.
