Abstract

The invention provides a colored-film substrate, and a preparation method and a liquid crystal display device thereof, and belongs to the field of display technique. Through the adoption of the colored-film substrate, the problem that columnar shock insulator objects and color element units in the existing colored film substrate can generate interference in the manufacturing process can reduce the quality of a displayed image, can be solved. According to the colored-film substrate, and the preparation method and the liquid crystal display device thereof, disclosed by the invention, alignment marks for forming the columnar shock insulator objects in the steps of forming the color element units are made, so that the pattern and the positional accuracy of the columnar shock insulator objects are ensured, and the possibility of generating interference between the columnar shock insulator objects and the color element units is reduced, and the quality of the displayed image is improved.

Description
