Abstract:
1. A light emitting device for displaying an image by dividing one frame into a plurality of subframes, comprising: a current source; a first wire; a second wire; a third wire; a fourth wire; a first light emitting element; a second light emitting element; a third transistor including a source and a drain one of which is electrically connected to the first wire and the other is electrically connected to one electrode of the first light emitting element; a first transistor including a source and a drain one of which is electrically connected to the second wire and the other is electrically connected to one electrode of the second light emitting element; a second transistor including a source and a drain one of which is electrically connected to a gate of the first transistor and the other is electrically connected to the third wire, and a gate that is electrically connected to the fourth wire; a circuit for turning the third transistor off when one electrode of the first light emitting element is short-circuited to the other electrode thereof; a circuit for supplying a potential generated using a potential of the first wire to the second wire; and a circuit for selecting the fourth wire more than once in any one of the plurality of subframes, wherein the first light emitting element is electrically connected to the current source through at least the first wire and the third transistor.
