Abstract

Abstract This invention relates to a stereoscopic image display apparatus which allows an observer to recognize a stereoscopic image, comprising right eye image display member for displaying an image for a right eye by irradiating light, left eye image display member for displaying an image for a left eye by irradiating light, and tilt member for tilting a central line, in a vertical direction, of an observation image which is formed based on the image for the right eye and is to be observed by the right eye of the observer, and a central line, in the vertical direction, of an observation image which is formed based on the image for the left eye and is to be observed by the left eye of the observer, relative to each other within a range from an angle larger than 0° to an angle not more than 3°.
