摘要： An image display device displays a stereoscopic image by using a parallax barrier method and includes a transmissive image display surface on which images of left-eye image data and right-eye image data are alternately displayed; an image forming unit including optical members having strip-shaped patterns with optical properties arranged on a surface located on a back surface side of the image display surface; and strip-shaped light sources arranged on an illumination arrangement surface, which is a surface located on a back surface side of the image forming unit, and configured to irradiate the image display surface with illumination light. A slit area of the parallax barrier method is formed by an image obtained by forming an image of the illumination light from the strip-shaped light sources on the back surface side of the image display surface by using the optical members of the image forming unit.
