Abstract

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.

Claims

exact text as granted — not AI-modified
What we claim is: 
     
         1 : A display device, comprising a plurality of pixel circuits,
 wherein at least one of the plurality of pixel circuits includes:   a drive transistor having a gate, a source and a drain electrode, and configured to supply a drive current from a power supply line to a light emitting element, the source electrode being directly connected to an anode electrode of the electro-optic element;   a capacitor having a first electrode connected to the source electrode and a second electrode connected to the gate electrode, and   wherein the drive transistor is an n-type TFT and includes amorphous silicon.
