Japanese Patent JP7446502
Kind Code:
B2
Abstract:
To suppress enlargement of pixel area even in the case of reducing current supplied to an electroluminescent element. A switch transistor, a first driving transistor, an electroluminescent element, and a second driving transistor provided between the first driving transistor and the electroluminescent element are included. A power supply potential is supplied to a gate of the second driving transistor. Drain current of the second driving transistor is controlled by the first driving transistor and the second driving transistor, so that a value of current supplied to the electroluminescent element is controlled.
