PROBLEM TO BE SOLVED: To enable a dark current interrupting device for vehicle to surely interrupt dark currents of a display circuit and also to make the device to be an inexpensive device. SOLUTION: This device is provided with light emitting diodes LED11, LED12, light emitting LED21, LED22, light emitting LED31, LED32, light emitting LED41 LED42 and first switching circuits GS1 to GS4 for green color, first switching circuits RS1 to RS4 for red color, first switching circuits BS1 to BS4 for blue color which are connected in serise with these light emitting diodes, a second switching circuit GS0 for green color, a second switching circuit RS0 for red color, a second switching circuit BS0 for blue color which are connected in series with light emitting diodes of the same color and when ON signals are not generated with respect to the second switching circuits, a power source to be supplied to these first switching circuits and the second switching circuits is interrupted with a single gate circuit AG.
