    • A color filter in accordance with the present invention comprises an activated film layer (2) arranged on a transparent substrate (1), said activated film layer (2) having a color pattern formed thereon by permeating a dye thereinto, and a thin metal film pattern (3) formed on a portion, of said activated film layer (2), which requires the formation of a black mask. Accordingly, the color filter integrated into various display devices such as a liquid crystal display is capable of displaying an image having a high contrast. Further, a method for forming a color filter in accordance with the present invention comprises the steps of forming an activated film layer (2) on a transparent substrate (1); permeating a dye into said activated film layer (2) to form a color pattern; and performing an electroless plating to form said thin metal film pattern (3) which functions as a black mask. Accordingly, the method in accordance with the present invention is capable of easily forming a color filter capable of displaying an image having a high contrast.
    • 根据本发明的滤色器包括布置在透明基板(1)上的活化膜层(2),所述活化膜层(2)通过将染料渗入其中形成在其上的彩色图案,并且薄金属膜 形成在所述活化膜层(2)的一部分上的需要形成黑色掩模的图案(3)。 因此,集成到诸如液晶显示器的各种显示装置中的滤色器能够显示具有高对比度的图像。 此外,根据本发明的形成滤色器的方法包括在透明基板(1)上形成活性薄膜层(2)的步骤。 将染料渗透到所述活化膜层(2)中以形成颜色图案; 并进行化学镀以形成用作黑色掩模的所述薄金属膜图案(3)。 因此,根据本发明的方法能够容易地形成能够显示具有高对比度的图像的滤色器。
