To provide a display device that enables multicolor expression at low cost and in a space-saving manner and is also improved in display responsiveness.
A display device 10 comprises: a heat source part 13; a heat conductive member 14 for conduction of heat from the heat source part 13; a temperature-indicating member 15 that changes in color by the temperature conducted from the heat conductive member 14; and a light transmissive member 17 that is fitted into an outer case 18 so as to cover the temperature-indicating member 15, and sandwiches the heat source part 13, the heat conductive member 14 and the temperature-indicating member 15 between the light transmissive member 17 itself and the outer case 18. The heat conductive member 14 includes a space part 14A for circulation of the heat generated from the heat source part 13.
