Abstract
Laser light beams are diffused and shaped by diffractive optical devices such that they are introduced to corresponding pixels of a liquid crystal layer over an entire area of a display region of a reflective liquid crystal panel. The diffused and shaped laser light beams are introduced to the reflective liquid crystal panel through a field lens and a polarizing beam splitter. Red, green and blue pixels are formed on the reflective liquid crystal panel, and a microlens array is formed on an incoming and outgoing side substrate while reflecting layers corresponding to the pixels are formed on a reflection side substrate. The laser light fluxes of the colors are distributed and condensed by the microlenses and introduced to the corresponding pixels and then reflected by the corresponding reflecting layers. Refractive optical devices may be used in place of the diffractive optical devices.
