Abstract

An image display apparatus has a signal input portion for receiving an image signal, an image compensator for electrically compensating the image signal for distortion so that a left and a right image displayed in an observer's left and right eyes have identical distortion and then outputting a left and right image signal that correspond to the left and right images, a signal switcher for switching between the left and right image signals output from the image compensator so as to output the left and right images alternately chronologically, a single two-dimensional image display device for displaying a two-dimensional image in accordance with the image signal output from the signal switcher, a pair of left and right eyepiece optical systems for directing image light exiting from the two-dimensional image display device to the observer's left and right eyes so that the two-dimensional image is displayed as a virtual image in the observer's eyes, and an optical path switcher for time-divisionally switching optical paths from the two-dimensional image display device to the observer's eyes in synchronism with switching between the left and right image signal output from the signal switcher so that the image light enters either the observer's left or right eye at a time.
