Abstract:
A liquid crystal display system comprising a liquid crystal cell system formed by sandwiching liquid crystals between a first transparent electrode substrate and a second transparent electrode substrate, the liquid crystal cell system thereby having a first transparent electrode substrate side and a second transparent electrode substrate side and a light source for projecting highly collimated light onto the first transparent electrode substrate, wherein an image is viewed from the second transparent electrode substrate side, wherein the improvement comprises that:an optical compensation means provided on each of the first transparent electrode substrate side and the second transparent electrode substrate side of the liquid crystal cell system; and a light dispersing layer is provided on the second transparent electrode substrate side of the liquid crystal cell system wherein the dispersing system disperses a projected light formed by said projecting, wherein a projection optical system is used as a back light of a liquid crystal display used for direct viewing.
