The invention relates to a method for patching a colored filter and a pre-patching material used thereby. The method for patching the colored filter comprises the following steps: firstly, providing a colored filter comprising a substrate and a colored filter layer which is configured on the substrate and provided with at least one defect pattern; secondly, forming a pre-patching layer in the at least one defect pattern; and thirdly, forming a patching layer connected with the substrate through the pre-patching layer on the pre-patching layer. The method and the material can improve the situation of poor adhesion between the patching layer and the substrate so as to improve the optical quality of the colored filter.
