Abstract: PURPOSE:To display all picture information even in case of such an abnormal case that part of a light source is absent by making the illumination state of the light source of a back light part and image information displayed on an image information display part correspond to each other. CONSTITUTION:When a 1st fluorescent lamp 13 has an absent point for some reason, the change of the absent point is detected by a 1st photodetection part 15 and an image signal generation part 11 includes image information of a part corresponding to the light emission surface of a back light 12 that light from the 1st fluorescent lamp 13 contributes to an image information of a part corresponding to the light emission surface of the back light 12 that light from a 2nd fluorescent lamp 14 contributes to as shown in a figure (c). The figure shows the compression of the information for including the information, but character information, etc., may be superposed on one open space while changed in color. Consequently, the reliable display device is obtained which displays all image information even in an abnormal state where part of the light source becomes absent.
