摘要： A first phase plate and a third phase plate, which constitute a polarizer structure, cooperate to impart a phase difference of a ¼ wavelength to linearly polarized light that emerges from a first polarizer plate. A second phase plate and a fourth phase plate cooperate to impart a phase difference of a ¼ wavelength to linearly polarized light that emerges from a second polarizer plate. Slow axes in planes of the first phase plate and the second phase plate are substantially parallel.

摘要： A phase difference plate for delaying the phase of incident light by &lgr;/4 and a liquid crystal layer for shifting the incident light by &lgr;/2 in accordance with an applied voltage are interposed between a polarization plate and a selective reflecting layer made of a cholesteric liquid crystal. A color filter layer is formed on the polarization-plate-side of the selective reflecting layer. A back-surface light source for emitting light having intensity peaks in a plurality of predetermined wavelengths is located on the back-surface of the selective reflecting layer. The selective reflecting layer is formed to transmit almost all light components in the plurality of small regions including the plurality of predetermined wavelengths and reflect almost all light components in regions between the plurality of small regions.
