Abstract
A light-emitting device includes a light-emitting element that emits light of an amount based on the size of a driving current; a driving transistor, the gate thereof being electrically connected to a first node, that outputs a current flowing between the drain-source as the driving current; and a control unit that supplies a first data potential to the first node and supplies a current to the driving transistor so as to set the voltage between the gate and source of the driving transistor to a compensated voltage based on the mobility of the driving transistor, and then supplies a second data potential determined in accordance with the first data potential to the first node.
