LATERAL ELECTRIC FIELD SWITCHING MODE TYPE LIQUID CRYSTAL DISPLAY

摘要

A lateral electric field switching mode type liquid crystal display satisfying color shift, corner irregularity and front contrast simultaneously. The lateral electric field switching mode type liquid crystal display, characterized in that a polarizing plate protective film used between a liquid crystal cell and a polarizer on the back light source side is a cellulose ester film having retardation values Ro and Rt in the range of 0nm=Ro=2nm and -10nm=Rt=10nm respectively, with the following Rt temperature variation of 7nm or less and Rt humidity variation of 20nm or less. Rt temperature variation; ?Rt value of the difference in Rt value measured after being left for 24 hours between under an environment of 23°C and relative humidity of 55% and under an environment of 35°C and relative humidity of 27%, Rt humidity variation; ?Rt value of the difference in Rt value measured after being left for 24 hours between under an environment of 23°C and relative humidity of 20% and under an environment of 23°C and relative humidity of 80%.
