    • Provided is an image display device including an image display cell and a polarizing plate placed on a viewer side of the image display cell. The first polarizing plate includes a polarizer and a first protective film. The first protective film is placed on a viewer-side principal surface of the polarizer and satisfies following relations: (i) 0 nm≦Re1≦3000 nm; (ii) Nz1≧7; and (iii) Rth1>2500 nm. Re1, Rth1 and Nz1 are defined by following equations: Re1=(nx1−ny1)d1; Rth1=(nx1−nz1)d1; and Nz1=Rth1/Re1, wherein d1 represents a thickness of the first protective film, nx1 represents a refractive index in a direction of an in-plane slow axis of the protective film, ny1 represents a refractive index in a direction of an in-plane fast axis of the protective film, and nz1 represents a refractive index in a direction of the thickness of the protective film.
    • 提供了一种图像显示装置,包括放置在图像显示单元的观察者侧的图像显示单元和偏振板。 第一偏振板包括偏振器和第一保护膜。 第一保护膜放置在偏振片的观察者侧主表面上,并且满足以下关系:(i)0nm≦̸ Re1≦̸ 3000nm; (ii)Nz1≥7; 和(iii)Rth1> 2500nm。 Re1,Rth1和Nz1由以下等式定义:Re1 =(nx1-ny1)d1; Rth1 =(nx1-nz1)d1; Nz1 = Rth1 / Re1,其中d1表示第一保护膜的厚度,nx1表示保护膜的面内慢轴方向的折射率,ny1表示保护膜的面内慢轴的折射率, 保护膜的平面快轴,nz1表示保护膜的厚度方向的折射率。

    • A method of manufacturing a polarizer is provided that makes it possible to manufacture a polarizer prevented from curling even when a liquid is brought into contact with a hydrophilic polymer film by being sprayed. A method of manufacturing a polarizer includes a swelling step A for swelling a hydrophilic polymer film 1 by bringing it into contact with a swelling liquid 2, a dyeing step B for dyeing the hydrophilic polymer film 1 by bringing it into contact with a dye liquid 3 containing a dichroic material, and a crosslinking/stretching step C for crosslinking the hydrophilic polymer film 1 by bringing it into contact with a crosslinking liquid 4 and further stretching it. In the method, the contact with the swelling liquid in the swelling step A is carried out in the gas phase by spraying the swelling liquid 2 onto both surfaces of the hydrophilic polymer film 1.
    • 提供一种制造偏振器的方法,其使得即使当通过喷射使液体与亲水性聚合物膜接触时,也可以制造防止卷曲的偏振片。 偏振片的制造方法包括:通过使其与溶胀液2接触来使亲水性高分子膜1溶胀的溶胀工序A,使亲水性高分子膜1与染料液3接触而染色的染色工序B 含有二色性材料的交联/拉伸工序C,使其与交联液4接触并使其进一步拉伸而使亲水性高分子膜1交联。 在该方法中,通过将溶胀液2喷雾到亲水性高分子膜1的两面上,在气相中进行溶胀工序A中的溶胀液的接触。

    • A coil bobbin includes: a body portion around which a coil is wound and having a cylindrical shape; a pair of flange portions formed at both ends of the body portion respectively; and terminal portions which are formed in the pair of flange portions, respectively, the terminal portions being around which respective ends of the coil are wound. The pair of flange portions have thicker portions and thinner portions, respectively, different from each other in thickness. The pair of flange portions is formed to gradually reduce a thickness from the thicker portions toward the thinner portions, respectively. The terminal portions are formed in the thicker portions, respectively.
    • 线圈架包括:线圈缠绕并具有圆柱形状的主体部分; 分别形成在主体部的两端的一对凸缘部; 以及分别形成在所述一对凸缘部分中的端子部分,所述端子部分绕在所述线圈的各个端部周围。 一对凸缘部分分别具有彼此不同厚度的较厚部分和较薄部分。 一对凸缘部形成为从较厚部分向较薄部分分别逐渐减小厚度。 端子部分分别形成在较厚的部分。
