A light emitting/receiving element includes: a substrate; an organic layer which is provided above the substrate; a forward bias power supply which applies a bias voltage between both ends of the organic layer so as to inject charges from an outside into the organic layer; a reverse bias power supply which applies a bias voltage, which is opposite in polarity to the bias voltage applied by the forward bias power supply, between the both ends of the organic layer so as to extract charges generated in the organic layer to the outside; and a current detecting unit, wherein the organic layer includes an organic material which, when the bias voltage is applied by the forward bias power supply, has the light emitting function, and which, when the bias voltage is applied by the reverse bias power supply, has the photoelectric converting function. |
