Reflection type liquid crystal display device with high-brightness bright display and high contrast

摘要

A reflection type liquid crystal display device which satisfies at least the performance requirements for high brightness in the bright display (white display) and a high contrast. Two phase difference plates and a polarizer are provided on an outer side of a liquid crystal cell and the liquid crystal layer is twisted by 240 to 250 degrees in its thickness direction and DELTAndLC for the crystal cell is from 600 nm to 800 nm; DELTAndRF1 for the first phase difference plate is from 100 nm to 200 nm, and the lagging axis beta of that phase difference plate forms an angle (phiRF1) Of 60 to 100 degrees in the counterclockwise direction as viewed from the light incidence side with respect to a normal direction X; DELTAndRF2 for the second phase difference plate is from 300 nm to 500 nm and a lagging axis gamma of that phase difference plate forms an angle (phiRF2) of 90 to 140 degrees in the counterclockwise direction as viewed from the light incidence side with respect to the normal direction X; and an absorption axis alphaof the polarizer forms an angle (phipo1) of 20 to 70 degrees or 110 to 160 degrees in the counterclockwise direction as viewed from the light incidence side with respect to the normal direction X.
