Assignee: FUJIFILM BUSINESS INNOVATION CORP.
Field: Semiconductors (Electrical engineering)
Classification: CPC H  G | IPC G  H

Claim 2:
3. A light-emitting device comprising:
one or more light-emitting units each comprising a light-emitting element and a first thyristor;
a first electrode to which a first voltage is applied for light emission of the light-emitting units; and
one or more second thyristors that permit the light-emitting element to emit light by a second voltage that is lower than the first voltage and set irrespective of the first voltage, wherein
the light-emitting element includes a planar light-emitting diode and the first thyristor is stacked on the planar light-emitting diode and causes the planar light-emitting diode to emit light when the first thyristor is in an on state.
