とから構成される調光表示装置。 A light emitting display section disposed at a position where it can be viewed directly by a viewer or at an appropriate position so as to be viewed by being projected by a reflective member, a brightness control section controlling light emission brightness of the light emitting display section, and the light emitting display section. In order to set the brightness of the external light detector, a set bias signal is added to the external light detection unit that detects the intensity of ambient external light and the detection signal corresponding to the external light intensity from this external light detection unit, and the intensity band of the detection signal is determined. A dimming display device comprising a bias setting section that shifts the amount of light.
