Abstract:
1. A light emitting part comprising: a plurality of light emitting thyristors that each have an anode and a cathode and that are lit in the on state; a light-on signal line that is connected with the cathodes or the anodes of the plurality of light emitting thyristors and that supplies current, the current which causes the plurality of light emitting thyristors to be lit; and a diversion thyristor that has an anode and a cathode, the anode or the cathode which is connected with the light-on signal line, and that diverts current, the current which flows to a light emitting thyristor to be lit among the plurality of light emitting thyristors in the on state, wherein a potential of the light-on signal line may be set so that the diversion thyristor and at least one light emitting thyristor among the plurality of light emitting thyristors become the on state in parallel.
