ABSTRACT:
Two liquid crystal panels for a first aspect ratio of, e.g., the conventional NTSC or PAL system are used to display an image having the first aspect ratio and an image having a second aspect ratio larger than the first aspect ratio by efficiently using the screens of the panels. For this purpose, right- and left-side liquid crystal panels (16R, 16L) for the first aspect ratio, for displaying images formed by an image signal at positions visible to only right and left eyes, respectively, and driving units (7-15, 17-19) for displaying identical images on the left and right liquid crystal panels when an image is to be displayed at the first aspect ratio, and divisionally displaying the image formed by the image signal on the left and right liquid crystal panels when the image is to be displayed at the second aspect ratio are provided.
