Abstract: A light-emitting thyristor includes a first semiconductor layer of a P type, a second semiconductor layer of an N type arranged adjacent to the first semiconductor layer; a third semiconductor layer of the P type arranged adjacent to the second semiconductor layer; and a fourth semiconductor layer of the N type arranged adjacent to the third semiconductor layer. A part of the first semiconductor layer is an active layer adjacent to the second semiconductor layer. A dopant concentration of the active layer is higher than or equal to a dopant concentration of the third semiconductor layer. A thickness of the third semiconductor layer is thinner than a thickness of the second semiconductor layer. A dopant concentration of the second semiconductor layer is lower than the dopant concentration of the third semiconductor layer.
