Abstract
A display device comprising the following arranged from light input side in the order listed below: a first reflector having a semi-transmissive and semi-reflective property; a translucent porous body having a plurality of pores in which a translucent material is filled, each of the pores having a substantially smaller diameter than the wavelength of input light; and a second reflector having a perfect reflection property, or a semi-transmissive and semi-reflective property. The average complex refractive index of the translucent porous body is changeable with respect to each display dot, and the wavelength of light absorbed by the translucent porous body is changeable with respect to each display dot according to the average complex refractive index. In this way, the input light is modulatable, and the modulated light is outputted from the first reflector and/or the second reflector to perform image display.
