Abstract
A couple of polarizers attached to LCD is one of the basic factors which determines the display quality and the reliability. In the application to LCD projection system, polarizers are requested to have increasingly high contrast consistent with adequate endurance under intense emission of light. A new dyed polarizer has been developed for this application. A neutral gray dichroic dye system has been composed by mixing two newly synthesized dichroic dyes with other several dyes. Using this system, dichroic dye polarizer provides superior polarizing ability of maximum CR equals 1,500 consistent with superior endurance of 1,000 hours under the surface illuminance between 1,500,000 and 2,200,000 lux at the temperature between 90 degree(s)C and 115 degree(s)C.
