CIRCULARLY POLARIZED PLATE, VERTICALLY-ORIENTED LIQUID CRYSTAL DISPLAY PANEL AND PRODUCTION METHODS FOR THEM |
摘要 |
A circularly polarized plate comprising a lambda/4 phase difference plate (1) and a linearly polarized plate (2) laminate on the main surface of the lambda/4 phase difference plate (1) so that its absorption axis forms an angle of about 45° with respect to the delay phase axis of the lambda/4 phase difference plate (1). The lambda/4 phase difference plate (1) has characteristics of reverse wavelength dispersion and an Nz coefficient of at least 1.6. The circularly polarized plate comprises the lambda/4 phase difference plate having characteristics of reverse wavelength dispersion and an Nz coefficient of at least 1.6, and the linearly polarized plate laminate on the main surface of the lambda/4 phase difference plate. When a reference direction is set as a direction parallel to one side of a rectangular flat shape, the circularly polarized plate is formed so that the delay-axis direction of the lambda/4 phase difference plate forms an angle of about +90° with respect to the reference direction, and the absorption-axis direction of the linearly polarized plate forms an angle of about +45° with respect to the reference direction. When any of these configurations is used, a circularly polarized plate excellent in viewing angle characteristics and a vertically-oriented liquid crystal display panel provided with this are provided. |
