摘要:
In a retardation film (c plate) for canceling the optical effect of a liquid crystal layer, the optical effect of the liquid crystal layer which is represented by Δnd/λ increases as the wavelength λ of incident light decreases. Accordingly, in order to cancel this effect, a negative retardation needs to be reduced as the wavelength of incident light increases. In a retardation film (a plate) for rotating the direction of polarization of light, an in-plane retardation needs to be increased as the wavelength λ of incident light increases. It is preferable that both of these retardation films be placed. However, compared to known technologies, light leakage can be suppressed even using only any one of the retardation films.
