ABSTRACT:
A display device that has a display screen is disclosed that has the ability to prevent reflections of the display screen from appearing on glass, without lowering the visibility of a display portion of the display screen. The brightness of the display color of either the background portion31on a display screen30or the background portion31of such one of display portions32and33as occupies the larger area of the lit portion of the display screen30is changed according to the control of a control switch23. If the brightness of the display color of the background portion31is lowered (from the “thin light blue” to the “thick light blue”, for example) at the nighttime, its reflection on the glass around a cabin40can be reduced without lowering the luminance of the display screen30. Alternatively, the saturation or hue of the display color can be changed to obtain a similar effect.
