PROBLEM TO BE SOLVED: To realize the display device that is able to drive drive elements at a low voltage regardless of input of a high voltage signal. SOLUTION: The display device is provided with a means 2 that provides an output of a superimposing signal VHF resulting from superimposing a low voltage signal VA on a power supply voltage VH, a transistor(TR) Q1 that is operated by the superimposing signal VHF, a switch element Q2 that receives an output signal from the TR Q1, and a resistor 6 connected between an input terminal and an output terminal of the switch element Q2. Then a collector current from the TR Q1 operated by the superimposing signal VHF causes a voltage across the resistor 6 and an ON/OFF state of a switch section of the switch element Q2 is controlled by using the voltage above. |
