Abstract
The three-dimensional image display apparatus of the present invention includes an optical modulator array which modulates the light intensity of an incident light to be an image signal light and an optical deflector array which shifts an image focusing position of each pixel light from the optical modulator array in the direction of an optical axis to form a three-dimensional section image, wherein the optical modulator array is formed of a diffractive type array in which a plurality of light reflective films are driven and correspond to a light of one pixel and the optical reflector array is formed of an array in which a plurality of light reflective films are driven and correspond to a light of one pixel.
