CIRCULARLY POLARIZING PLATE AND LIQUID CRYSTAL DISPLAY DEVICE |
摘要 |
PROBLEM TO BE SOLVED: To provide a circularly polarizing plate with excellent circular polarization characteristics and a semitransmissive liquid crystal display device with a bright display, with high contrast and with little viewing angle dependence in a transmissive mode. SOLUTION: The circularly polarizing plate at least comprises a polarizing plate and an optically anisotropic element with a phase difference of nearly a quarter of a wavelength in the visible ray region and is characterized by having the optically anisotropic element comprising at least a liquid crystal film with a fixed nematic hybrid alignment structure. The liquid crystal display device is provided with the circularly polarizing plate. |
