The present invention relates to the field of color filters, in
particular, to a non-absorbing polarization color filters and to
high-brightness color liquid crystal display panel with improved image
contrast employing non-absorbing polarization color filters and light
recycling among neighboring subpixels. The disclosed invention represents
a non-absorbing polarization color filter comprising the following
elements: a rear broadband multilayer lossless polarizer, a front
broadband multilayer lossless polarizer, and a color polarization
rotator. The rear broadband multilayer lossless polarizer has a
predefined-oriented transmission axis AB. Said front broadband multilayer
lossless polarizer is located approximately in parallel with the rear
broadband multilayer lossless polarizer, and has a transmission axis
approximately parallel or approximately orthogonal with respect to
transmission axis AB. The color polarization rotator is located between
the front broadband multilayer lossless polarizer and the rear broadband
multilayer lossless polarizer. Said color polarization rotator comprises
a stack of thin birefringent films with c-axes orientations alternated in
sign according to a rocking angle .alpha. with respect to orientation of
the transmission axis AB. A number, a rocking angle .alpha., thicknesses
and optical anisotropies of thin birefringent films are selected so, that
the non-absorbing polarization color filter transmits a predetermined
color light having the polarization state approximately parallel to
transmission axis AB, reflects said predetermined color light having the
polarization state orthogonal to the transmission axis AB, and reflects
an unpolarized light of other predetermined color.
