METHOD FOR IMPROVING OPTICAL RESPONSE AND LIQUID CRYSTAL DISPLAY DEVICE USING SAME

摘要

The present invention provides a method for improving the optical response to the time variation of the transmitted light amount of a liquid crystal display element. In the liquid crystal display element 1 having the liquid crystal cell 2 having the liquid crystal layer and the first polarizing plate 3 and the second polarizing plate 4 and the optical compensating plate 5 , The differential coefficient for the time t of the transmitted light amount I _{1 at} the time of dropping of the drive voltage when the arrangement of the optical compensation plate 5 is omitted is defined as ∂ Ι ₁ / ∂t, and the optical compensation plate 5 (1): | ∂Ι ₂ / ∂t | | ∂Ι ₁ / ∂t, where ∂Ι ₂ / ∂t is the differential coefficient with respect to the time t of the transmitted light amount Ι _{2 at} the time when the driving voltage is decreased ∂t | ... (1), by performing optical design of the phase difference of the liquid crystal layer and the phase difference of the optical compensation plate 5, the optical response at the time of descending (off) from the voltage V1 of V1 V2 to the voltage V2 .
