Abstract:
A light emitting device includes a light emitting element, a driving transistor configured to control driving of the light emitting element, a threshold correction unit configured to perform compensation for a voltage corresponding to a threshold of the driving transistor, and an electric potential setting unit configured to set an electric potential of a node between the driving transistor and the light emitting element, wherein the electric potential setting unit sets a first electric potential and a second electric potential different from the first electric potential, at the node.
