Abstract
A light-emitting component includes an insulating substrate, plural light-emitting elements, and plural thyristors. The plural light-emitting elements are disposed on the substrate and constituted by a first stacked semiconductor layer, the first stacked semiconductor layer being obtained by stacking plural semiconductor layers. The plural thyristors are constituted by a second stacked semiconductor layer disposed on the substrate such that the light-emitting elements and the thyristors are arranged side by side, connected to the plural light-emitting elements, respectively, and turn on to drive the light-emitting elements to emit light or to increase an emitted light amount, the second stacked semiconductor layer being obtained by stacking plural semiconductor layers that are different from the semiconductor layers of the first stacked semiconductor layer.
