ABSTRACT:
A color liquid crystal display device includes a liquid crystal element, an optical path conversion element array and a hologram. The liquid crystal element has a blue pixel B, a red pixel R, and a green pixel G, which are arranged plainly, and a liquid crystal layer. The optical path conversion element array converts external light into approximately parallel light. The hologram separates light from the optical path conversion element array into a light having a wavelength range of the three primary colors and irradiates pixels R, G and B corresponding to the liquid crystal element.
