| 摘要 |
A polarizer has low color shift and is particularly well suited to use in an LCD display. The polarizer has a double pass color shift of | DELTA x0&verbar </= 0.005 and | DELTA x0&verbar </= 0.005 for illumination by a C-illuminant, and a double pass contrast modulation of at least 90 %. The display includes two or more layers stacked together, at least one of the layers being an absorbing polarizer having a double pass color shift of | DELTA x0| </= 0.005 and | DELTA x0| </= 0.005 for illumination by a C-illuminant. A polarizer with a selected color shift is also used with a rear projection screen having a dispersing layer stacked together with first absorbing polarizer. The polarizer has a single pass color shift with at least one of DELTA x and DELTA y being negative under illumination by a C-illuminant, and a polarization co-efficiency greater than 90 %. |
