Pixel circuit and display device

1. A pixel circuit configured to emit light based on an image signal, the pixel circuit comprising:

a light emitting element;

a driver transistor configured to adjust current supplied to the light emitting element; and

a write transistor connected between a signal line to which the image signal is applied and the driver transistor,

wherein the driver transistor includes:

a gate electrode;

a counter electrode disposed opposite the gate electrode; and

a channel disposed between the gate electrode and the counter electrode, and

a potential applied to the counter electrode in a write period in which the write transistor conducts current in a state in which the image signal is applied to the signal line reduces a resistance value of the driver transistor to a lower value than a potential applied to the counter electrode in an emission period of the light emitting element does,

wherein the pixel circuit further comprises a pair of switching transistors connected to the counter electrode;

wherein the potential applied to the counter electrode is selected according to ON and OFF states of the pair of switching transistors, and

wherein the pair of switching transistors includes an N-channel transistor and a P-channel transistor that share a gate.

2. The pixel circuit according to claim 1 ,

wherein a gate potential of the N-channel transistor and the P-channel transistor is equal to a gate potential of the write transistor.
