发明名称 Color filter and method of making the same
摘要 A color filter and a method of making the same are disclosed. The method for fabricating a color filter has the steps of: providing a substrate; forming a black matrix layer on the substrate; using a mask to form at least one first light-filtering pattern on the substrate provided with the black matrix layer; using the mask to form at least one second light-filtering pattern on the substrate provided with the black matrix layer and the first light-filtering pattern; using the mask to form at least one third light-filtering pattern on the substrate provided with the black matrix layer, the first light-filtering pattern and the second light-filtering pattern, wherein the mask has different transmission spectra corresponding to the first light-filtering pattern, the second light-filtering pattern and the third light-filtering pattern, respectively.

主权项 1. A method for fabricating a color filter, comprising the steps of: providing a substrate; forming a black matrix layer on the substrate; coating a first photoresist material on the substrate provided with the black matrix layer, and forming at least one first light-filtering pattern through a mask by ultraviolet exposure and developing the substrate coated with the first photoresist material which has a photosensitive frequency in a transmission spectrum range of the mask corresponding to the first light-filtering pattern; coating a second photoresist material on the substrate provided with the black matrix layer and the first light-filtering pattern, and forming at least one second light-filtering pattern through the mask by ultraviolet exposure and developing the substrate coated with the second photoresist material which has a photosensitive frequency in a transmission spectrum range of the mask corresponding to the second light-filtering pattern; and coating a third photoresist material on the substrate provided with the black matrix layer, the first light-filtering pattern and the second light-filtering pattern, and forming at least one third light-filtering pattern through the mask by ultraviolet exposure and developing the substrate coated with the third photoresist material which has a photosensitive frequency in a transmission spectrum range of the mask corresponding to the third light-filtering pattern.
