Abstract

A display unit includes a light-emitting element array having a plurality of linearly arranged light-emitting elements drivable by a time sequential image information signal to emit beams of light in accordance with pieces of information allotted to the corresponding picture elements, a deflector such as a polygon mirror for deflecting the light beams simultaneously in a direction perpendicular to the longitudinal direction of the light-emitting element array, and a light-to-light conversion element including a photoconductive layer and a photo-modulation layer, the light beams being imaged on the photoconductive layer.
