Abstract
In a liquid crystal display deviceincluding a liquid crystal cellhaving a liquid crystal layer, a first polarization plateand a second polarization plate, and an optical compensation plate, when a differential coefficient of the amount of transmitted light Iwith respect to a time t when the driving voltage is turned off from on in a case in which the optical compensation plateis not disposed is represented by ∂I/∂t, and a differential coefficient of the amount of transmitted light Iwith respect to the time t when the driving voltage is turned off from on in a case in which the optical compensation plateis disposed is represented by ∂I/∂t, a phase difference in the liquid crystal layer and a phase difference in the optical compensation plateare optically designed to satisfy a relationship of |∂I/∂t|>|∂I/∂t|.
