ABSTRACT:
A color filterless display device performing color display for expressing one pixel by three RGB sub-pixels includes: a light source; a diffraction grating for separating a light irradiated from this light source into lights of a plurality of wavelength regions; a cylindrical lens array for receiving the separated light and condensing the light while corresponding to each of the sub-pixels; and a liquid crystal cell including a structure portion for correcting an angle of the condensed light for all sub-pixels, wherein, in the structure portion of this liquid crystal cell, a side onto which a light from the cylindrical lens array is made incident is made of a high refractive index layer, an emitting side from which the light is emitted is made of a low refractive index layer, and a Fresnel-type microprism structure is formed by the high refractive index layer and the low refractive index layer.
