ABSTRACT:
A light source (60) is provided in the rear of display means (30), which has a light transmission type display and is made up of pixels (31) for left and right eyes and a first image separation mechanism (32) for the left and right eyes, with a lens unit (41) having a collecting power in a vertical direction and a second image separation mechanism (52) therebetween. The transmission light from the light source (60) spreads in the vertical direction as shown in the drawing. Such spread of the light occurs over the whole of a display surface. It is therefore possible to view the image on the display surface, when the viewer's head is located at any of positions1to4. Accordingly, it becomes possible to make a degree of freedom in vertical (up-and-down) positional movement of the viewer's head.
