Abstract:
An image display apparatus 100 includes: (A) an image generating device 111 including a light source 160 and a transmissive spatial light modulating device 150 formed with pixels 152 arranged in a two-dimensional matrix; and (B) a light guiding unit 120 that guides light from the image generating device 111, and emits the light toward an eye 21 of a viewer 20, wherein the transmissive spatial light modulating device 150 includes, on a light emitting side thereof, a microlens array 170 including a microlens corresponding to each pixel, and when an incident solid angle of light entering a pixel from the light source 160 is assumed to be ωin, and an emitting solid angle of light that passes through the pixel and is emitted from the microlens corresponding to the pixel is assumed to be ωout, ωout>ωin is satisfied.
