1. A display device comprising:
a first light-transmitting substrate;
a second light-transmitting substrate opposed to the first light-transmitting substrate;
a liquid crystal layer between the first light-transmitting substrate and the second light-transmitting substrate;
a first electrode and a second electrode disposed so as to sandwich the liquid crystal layer; and
a light emitter comprising a first light emitter configured to emit light in a first color, a second light emitter configured to emit light in a second color, and a third light emitter configured to emit light in a third color, wherein
the first light emitter has a temperature characteristic in which a relative light intensity decreases more with increase in a heating temperature than in the case of the second light emitter and the third light emitter, and
the first light emitter is configured to be driven in a state where an amount of light thereof is multiplied by a coefficient smaller than those of the second light emitter and the third light emitter.
