Abstract:
A display device including pixel circuit groups containing pixel circuits. The pixel circuit groups each contain: a first transistor whose first terminal is connected to a power source potential line; and a sixth transistor whose control terminal is connected to a first scanning signal line and whose first terminal is connected to an image signal line. The pixel circuit each include: a second transistor whose control terminal is connected to a first node and whose first terminal is connected to a second terminal of the first transistor and a second terminal of the sixth transistor; a third transistor whose first terminal is connected to the first node and whose second terminal is connected to a second terminal of the second transistor; a fourth transistor whose first terminal is connected to the second terminal of the second transistor; and a fifth transistor whose first terminal is connected to the first node.
