PROBLEM TO BE SOLVED: To prevent a decrease in the number of gray scales that is expressed while simplifying configuration for suppressing a change of light emission luminance associated with temperature rise of a panel.SOLUTION: The light emitting device 100 includes: a pixel circuit U including a driving transistor TDR arranged between a first feeder 14 and a second feeder 16, and generating driving current when supplying on-potential to a gate, and a light emitting element E arranged between the first feeder 14 and the second feeder 16, and emitting light by supply of the driving current; a driving circuit 40 supplying on-potential or off-potential to the pixel circuit U; and a control circuit 30 variably controlling voltage Vdd so that a difference between a value of the driving current flowing in the light emitting element E and a target value of the driving current may be within a prescribed range. |
