[0054] In the sixth embodiment of the present invention, a method for manufacturing a color filter includes the following steps: providing a substrate with several high platforms on the surface; coating color ink on the high platforms and forming a colored layer on the surface of the high platforms; A black matrix is formed on the area between, and the colored layer is not in contact with the black matrix.
[0055] The substrate of this embodiment is generally a plastic substrate, which is integrally formed by injection molding. The process and materials of the black matrix and the colored layer are the same as those of the black matrix 12 and the colored layer 15 in the second embodiment, or the black ink is coated by inkjet to form the black matrix.

Abstract
The invention relates to a color filter. The color filter includes a substrate, a black matrix and a colored layer, wherein a high platform higher than the black matrix is arranged between the black matrix, the colored layer is located on the surface of the high platform, and the colored layer is not in contact with the black matrix . The present invention also relates to a method for manufacturing a color filter, the method comprising the following steps: providing a substrate; forming a plurality of black matrices on the substrate; forming high platforms higher than the black matrix between the black matrices; coating ink and form a colored layer on the surface of the platform, and the colored layer is not in contact with the black matrix.
Description
【Technical field】 [0001] The invention relates to a color filter and a manufacturing method of the color filter. 【Background technique】 [0002] Liquid crystal display (LCD) is widely used in personal computers, televisions and other fields due to its excellent picture quality, external size and low power consumption. In recent years, the LCD industry has developed rapidly and continues to develop in the direction of high precision and large screen . In color LCD products, color filters are essential components. [0003] LCD is a non-active light-emitting element. Its color display must be provided by its own light source device or external ambient light. The grayscale display is formed through the driver and controller, and then the color filter is used to generate red (Red) and green (Green). , Blue (Blue) three primary colors, based on the principle of color mixing to form a color display screen. [0004] A color filter generally consists of a glass substrate, a black ...
