PROBLEM TO BE SOLVED: To provide a display device free from occurrence of irregular luminance on a multi-display screen.;SOLUTION: Any of the respective display devices 2 constituting the multi-display screen is set as representation, and illuminance detected by a sensor 18 of the display device 2 set as the representation, that is, illuminance around the screen of the display device 2 set as the representation, is obtained. Then, luminance corresponding to the illuminance is obtained, and the luminances on the screens of the respective display devices 2 are adjusted to the obtained luminance, whereby the luminances on the screens of the respective display devices 2 are uniformized. By cyclically performing such luminance adjustment, the luminances are varied in accordance with an illuminance change around the screen of the display device 2 set as the representation. By fitting the luminance on the multi-display screen to ambient brightness, the multi-display screen is prevented from getting hard-to-view whether it is dark or bright.;COPYRIGHT: (C)2009,JPO&INPIT
