Abstract

A light-emitting element having a light-emitting section and a light-receiving section provided on a substrate. The light-emitting section includes: an organic compound in which light is emitted; a translucent reflecting portion that transmits the emitted light which has spectral radiance changeable with changes in ambient temperature; and a transparent portion that radiates first part of the light coming through the translucent reflecting portion to outside and total-reflects second part that is light incident to a boundary surface therebetween at angles larger than a critical angle. Wherein, the light-receiving section is capable of receiving the light total-reflected at the boundary surface, the received light having a quantity of light changeable with changes in wavelength of the light passing through the translucent reflecting portion. The light-receiving section further outputs a signal which has an amplitude level in correlation to the quantity of light.
