A pixel drive circuit includes a drain voltage increase limiter circuit composed of a TFT device provided between a node and the drain of a TFT device serving as a current source, a capacitor and a switch. In a data write mode, switches are turned on to allow drive current to flow from a data line to the TFT devices. Then, respective gate voltages of the TFT devices are held in respective capacitors. In a display mode, only a switch is turned on to form a current path from a supply voltage to the TFT devices through a light-emitting diode. The voltage on a node is held constant regardless of channel modulation. Accordingly, desired electric current flows through the light-emitting diode.
