Problems solved by technology

[0016] However, in the existing manufacturing method of the color filter structure 10, since the spacers 15a are to be fabricated by exposure and development at last, the steps of forming the photoresist layer 15, making a mask, and exposure and development must be performed.
Therefore, its manufacturing process is relatively complicated and the required manufacturing cost is relatively high, thereby increasing the manufacturing cost of the color filter structure 10

Abstract

The invention discloses a structure of a CF and a manufacture method thereof. The CF structurally comprises a glass substrate, a black matrix, a color layer, a plurality of interstitials, an ITO (indium tin oxide), and a transparent planarization light resistance layer. By the adoption of the invention, when the color layer is manufactured, the plurality of interstitials can be formed by using the same color resistance material at the same time, therefore, the structure of the CF provided by the invention has the advantages of simplicity and lower cost, thereby saving the manufacturing cost; additionally, the transparent planarization light resistance layer can avoid short circuit of the ITO during the assembly process.

Description

【Technical field】 [0001] The invention relates to the technical field of liquid crystal panels, in particular to a color filter structure and a manufacturing method thereof. 【Background technique】 [0002] A liquid crystal display (Liquid Crystal Display, LCD) is a flat panel display device (Flat Panel Display, FPD) that uses the characteristics of liquid crystal materials to display images. Power consumption and other advantages have become mainstream products in the entire consumer market. [0003] The current liquid crystal display manufacturing process can be roughly divided into the front-end array (Array) process, the middle-end cell (Cell) process and the rear-end modular (Module) process. The matrix process in the previous stage is to produce thin-film transistor (TFT) substrates and color filter (Color Film) substrates. The mid-stage box forming process is responsible for combining TFT substrates and CF boards, injecting liquid crystals between the two and cutting...
