Patent ID: 7755593

Claim:
A display device mounted to a mode of transport comprising: a first display area that is fixed with respect to the display device; and a second display area that is fixed with respect to the display device, that is separate from the first display area, and that is closer to a position of an operator than is the first display area when the display device is mounted to the mode of transport; a first luminance level output section arranged to output a first luminance level representing luminance of an image display produced in the first display area; a second luminance level output section arranged to output a second luminance level representing luminance of an image display produced in the second display area; and a luminance limiting section arranged to limit, according to the first luminance level and the second luminance level, the luminance of the image display produced in the first display area to be less than the luminance of the image display produced in the second display area; wherein the first and second display areas are provided on a transmissive liquid crystal display device with separate backlights for each of the display areas; and the luminance limiting section regulates output optical intensity of at least one of the separate backlights, and the luminance level of the first display area is non-zero.
