Abstract: The present invention relates to a projector having an arrangement of polarizers and liquid crystal cells aligned on an axis of light. The order of the polarizers and cells is a first color polarizer colored in red, a first twisted nematic liquid crystal cell, a second twisted nematic liquid crystal cell, a second color polarizer colored in green, a third twisted nematic liquid, a neutral polarizer and a Guest-Host type colored in blue. Since, according to this, a polarizer having inferior color characteristics can be replaced by a Guest-Host type liquid crystal cell, the excitation purity and the scope of color reproduction are improved. Further, since the mixture of color is additive, the brightness of the reproduced color is also much improved.
