    • A polarizing plate is disclosed, comprising a polarizing film and a protective layer bonded through an adhesive layer to at least one surface of the polarizing film, wherein the protective layer is a polyester film in which the minimum or maximum refractive index in a direction in parallel with the plane of the film is nearly equal to that in the direction of the film thickness and the retardation is at least 10 .mu.m. On this polarizing plate, colored interference fringes are not formed at all even if it is looked at from any direction. Thus, the polarizing plate is suitable for use in the circumstance that it is exposed to the air, or in a display wherein a liquid crystal is used.
    • 公开了一种偏振片,其包括偏振膜和通过粘合剂层粘合到偏振膜的至少一个表面的保护层,其中保护层是其中平行方向上的最小或最大折射率的聚酯膜 膜的平面几乎等于膜厚度方向,延迟至少为10微米。 在这种偏光板上,即使从任何方向观察,都不会形成彩色的干涉条纹。 因此,偏光板适合用于暴露于空气的环境中,或者在使用液晶的显示器中使用。

    • A transparent laminate is constituted by a transparent substrate, a low refractive index transparent thin film formed on a surface of the transparent substrate, between three and five combination layers laminated successively on a surface of the first low refractive index transparent thin film, another high refractive index transparent thin film formed on a surface of the combination layers, and an outermost layer. The combination layers has high refractive index transparent thin films and silver type transparent electrical conductor thin films, each combination layer having one high refractive index transparent thin film and one silver type transparent electrical conductor thin film. The outermost layer is stuck through a transparent adhesive agent layer onto a surface of the high refractive index transparent thin film farthest from the transparent substrate. The outermost layer is at least one of selected from the group of consisting of an anti-reflection film, an anti-mirroring film and a low reflection anti-mirroring film. The low refractive index transparent thin film is an optically transparent thin film having a refractive indexing in a range of 1.3 to 1.6 and each of the high refractive index transparent thin film is an optically transparent thin film having a refractive index nH in a range of from 1.9 to 2.5.
