Light Emitting Device, Electronic Device, and Method for Driving Pixel Circuit

A light emitting device includes: a pixel circuit; and a driving circuit that drives the pixel circuit, wherein the pixel circuit includes: a light emitting element; a driving transistor that is connected to the light emitting element in series; a storage capacitor that is located between a gate of the driving transistor and a source of the driving transistor; and a selecting transistor that is located between the gate of the driving transistor and a signal line that corresponds to the pixel circuit, after a writing period starts, the driving circuit sets a potential of a selection signal to a selection potential to turn on the selecting transistor and outputs a data potential to the signal line to cause a current corresponding to the data potential to flow in the driving transistor, the selection signal being to be supplied to the gate of the selecting transistor, the data potential being changed over time, and after the driving circuit sets the potential of the selection signal to the selection potential and outputs the data potential, the driving circuit changes, from the selection potential, the potential of the selection signal over time until the end time of the writing period to turn off the selecting transistor and thereby stop supply of the data potential and sets, to a rate corresponding to a gradation specified for the pixel circuit, a rate of change of the data potential at the time when the supply of the data potential to the driving transistor is stopped.
