The indicator light is turned on and off by a detection transistor that detects a change in the information signal of the corresponding detection terminal, a switching transistor that is turned on by the operating current of the detection transistor, and a drive transistor that is turned on by the on operation of this switching transistor. At the same time, a diode is interposed between the drive transistor of the indicator lamp that is displaying the lighting display and the drive transistor of the indicator light that is displaying the next display, which turns off the former drive transistor when the latter drive transistor is turned on. Display device.
