PROBLEM TO BE SOLVED: To provide a display device capable of accurately performing gradation display and binary display with a simpler configuration. SOLUTION: An interference filter M1 is provided with, for example, a Fabry- Perot resonator and a bandpass filter. Thus, the Fabry-Perot resonator selectively transmits light of a desired wavelength. In the case light other than the light of a desired wavelength transmits from the Fabry-Perot resonator, the bandpass filter interrupts the light. The transmission factor of light that transmits the interference filter M1 can be adjusted in such a manner an incidence angle changing part M2 changes an incidence angle of the light. |
