    • A color cathode-ray tube has a black matrix film having a plurality of light-transmitting windows that are formed on an inner surface of a face panel to have a predetermined positional relationship with each other, filter films formed in the light-transmitting windows to correspond to green, blue, and red, and phosphor films formed by stacking green, blue, and red phosphors on inner surfaces of the filter films. The filter films are made of a photo-tacky resin containing a filter dispersion. A method of manufacturing this color cathode-ray tube is also provided. This method includes the steps of applying a photo-tacky resin containing a desired filter dispersion to the inner surface of the face panel where the back matrix film is formed in advance, exposing the photo-tacky resin in the light-transmitting windows through a shadow mask, applying and drying a phosphor slurry to form the phosphor films, and removing undesired, non-exposed portions of the photo-tacky resin and phosphor films simultaneously.
    • 彩色阴极射线管具有黑矩阵膜,该黑矩阵膜具有多个透光窗,该多个透光窗形成在面板的内表面上以具有预定的位置关系,在透光窗中形成滤光膜至 对应于绿色,蓝色和红色,以及通过在滤膜的内表面上堆叠绿色,蓝色和红色磷光体形成的荧光膜。 过滤膜由含有过滤分散体的光敏树脂制成。 还提供了一种制造该彩色阴极射线管的方法。 该方法包括以下步骤:将预期的过滤分散体的光胶树脂预先涂覆在面板的内表面上,使透光窗中的光粘着树脂通过阴影曝光 掩模,施加和干燥磷光体浆料以形成荧光膜,同时去除光敏树脂和荧光膜的不期望的,未曝光的部分。
