发明名称 PHASE DIFFERENCE PLATE AND LIQUID CRYSTAL DEVICE PROVIDED WITH THE SAME
摘要 PROBLEM TO BE SOLVED: To provide a phase difference plate capable of improving whole visual filed angle characteristic of a liquid crystal panel of an inplane mode and a liquid crystal device provided with the same. SOLUTION: Discotic liquid crystal molecules 34 are arranged and fixed on a transparent planar body 33 to form a phase difference layer 31 and, meanwhile, the liquid crystal molecules 34 are arranged and fixed so that disk planes thereof are vertical or almost vertical to the facial direction of the transparent planar body 33 at the time of forming the phase difference layer 31. Thereby, the optical axis of the phase difference plate 3 having optically minus uniaxial anisotropy is made parallel or almost parallel to the facial direction thereof. Then, leakage light at the time of displaying black on the liquid crystal display panel in a mode in which the bar-shaped liquid crystal molecules are always parallel or almost parallel to the facial direction of a glass substrate is reduced by providing the phase difference plate 3 between a pair of glass substrates holding the bar-shaped liquid crystal molecules having positive uniaxial anisotropy and a pair of polarizing plates mounted on outer surfaces of the glass substrates.
