| 摘要 | A display device includes a light emitting diode that emits a light in response to a current supplied thereto, a constant current circuit that includes a first transistor to control an amount of the current supplied to the light emitting diode, and a pixel circuit that includes a switching circuit including a second transistor to switch the supply of the current to the light emitting diode and a capacitor including a first terminal connected to a gate terminal of the second transistor and a second terminal connected to a signal line that changes a voltage of the other terminal. The first transistor and the second transistor are connected between a first power supply line and an anode of the light emitting diode including a cathode connected to a second power supply line in series. | ||
