PROBLEM TO BE SOLVED: To provide a display device which is simple in composition and switches from a plurality of display forms to one display surface for a display. SOLUTION: A first selection display layer 27a formed on a base material layer 26 is composed of a first transmission section 28a and a first mask 29a. The first transmission 28a comprises a material which can transmit any of three primary color light emitted form a light source. The first transmission section 28a is formed in a display form, for example, a shape of a numeral, and is surrounded by the first mask 29a. The first mask 29a surrounding the first transmission section 28a is composed of a light selecting-and-absorbing material having a function which absorbs incident light of specific wavelength range, for example, R light, which is emitted from the light source and is made incident, and makes another light having a wavelength range different from that of the R light pass through when another light is made incident.
