Abstract:
An organic electroluminescent display device includes: a display unit in which pixels are arranged in rows and columns, the pixels each including an organic electroluminescent element, a drive transistor, and a capacitor; a power supply unit which generates a supply voltage; a gate drive unit which applies a reference supply voltage to the capacitor; and a control unit which carries the supply voltage from the power supply unit to the gate drive unit, wherein the gate drive unit includes a buffer amplifier circuit which suppresses a variable component of the supply voltage carried via the control unit to stabilize the reference supply voltage, and supplies the stabilized reference supply voltage to the pixel.
