摘要： A display device including a diffraction grating from which a diffracted light of the zeroth order and a diffracted light of the first order having different color light components emerge to establish color separation. An array of micro-lenses is arranged on a liquid crystal panel. The liquid crystal panel has a plurality of picture elements and each picture element includes a plurality of color display dots. The color display dots in each picture element are arranged in the vertical relationship and in the order of wavelength of the light. A green light component of diffracted light of the first order is made incident normal to the liquid crystal panel, and the diffracted light of the zeroth order passes through the liquid crystal panel at a greater angle relative to the normal to the liquid crystal panel.
