PIXEL CIRCUIT AND DISPLAY DEVICE

摘要

A pixel circuit able to prevent a spread of the terminal voltages of drive transistors inside a panel and in turn able to reliably prevent deterioration of uniformity, wherein a source of a TFT serving as a drive transistor is connected to an anode of a light emitting element, a drain is connected to a power source potential, a capacitor is connected between a gate and source of the TFT, and a source potential of the TFT is connected to a fixed potential through a TFT serving as a switch transistor and wherein pixel circuit lines are connected by an upper line and bottom line and are arranged in parallel with pixel circuit power source voltage lines so as not to have intersecting parts.

1. A pixel circuit for driving an electro-optic element, comprising:
a drive transistor; a first node; a first power source; a second power source; and a first circuit for connecting said first node to said second power source while said electro-optic element is not emitting light; said drive transistor, said first node, and said electro-optic element being connected in series between said first power source and said second power source; the first power source and said second power source being laid out along a same direction.
