Transflective liquid crystal display device with particular angle relationships between the half wave plate and polarizers
Abstract:
A transflective LCD device improves a light transmittance in both the transmissive mode and the reflective mode and improves efficiency in the use of the light regardless of wavelength. To properly control the ON/OFF-switch of the blue wavelength band or the red wavelength band, the transflective LCD device adopts a half wave plate (λ/2) and changes the optic axes of the polarizers and the retardation film.
