An image display device includes a display element having a unit of display comprising sub pixels displaying images for first and second view points, and an optical unit that distributes light emitted from respective sub pixels into different first directions. When a region surrounded a black matrix in the sub pixel is defined as an aperture, the sub pixels form a base unit that is an adjoining pixel pair including two sub pixels arranged with a data line therebetween.

A planar light source, Fresnel lens sheet, and louver are disposed in the stated order in a light source apparatus. The Fresnel lens sheet deflects and focuses in one dimension light that has entered from the planar light source. The louver is disposed in the optical path of the light emitted from the Fresnel lens sheet, and the directivity of the light can be increased by restricting the traveling direction of the light to the focal direction of the Fresnel lens sheet. The light utilization ratio can thereby be increased, the directivity of planarly emitted light can be increased, and the brightness can be made uniform at the point of observation.
