A photoelectric sensitive display for motorcar fuel content is characterized in that when a photoconductive resistor is irradiated by lights (visible lights), the resistance (bright resistance) of the photoconductive resistor pair gets smaller and is in an ''ON'' state, when no light irradiates the photoconductive resistor pair, the resistance (dark resistance) gets bigger and is in an ''OFF'' state; when the oil in an oil tank is ''FULL'', all the lights irradiate a plurality of predetermined photoconductive resistors, all of display LEDs are bright; when the oil tank is ''EMPTY'', all the lights are shielded and all the display LEDs are dark; when the oil in the oil tank is ''PART'', a part of the lights irradiate the photoconductive resistors and a part of the display LEDs are bright.
