Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a color filter, a light sheet substrate, a method of manufacturing the same, and a liquid crystal display panel using the same, and more particularly to an inner and outer opening of a black matrix. A color filter substrate having different surface characteristics, a method of manufacturing the same, and a liquid crystal display panel using the same. [Prior Art] The conventional liquid crystal display panel includes a thin film transistor substrate, a color filter substrate, and a liquid crystal layer, and the liquid crystal layer is disposed between the thin film transistor substrate and the color filter substrate disposed in parallel with each other. In the thin film transistor substrate, an active matrix element array is formed on a glass substrate. The active matrix pixel array has a plurality of pixels, each of which is defined by two scan lines parallel to each other and two data lines parallel to each other. Each element includes a thin film transistor and a halogen electrode, and the thin film transistor is electrically connected to one of the scanning lines and one of the data lines, and the halogen electrode is electrically connected to the thin film transistor. The scan driving circuit turns on each of the thin film transistors through the scanning line, and the data driving circuit supplies the pixel voltage required for each row of pixels through the data line. Wherein, in the case where the thin film transistor is turned on, the pixel electrode obtains a desired pixel voltage via the opened thin film transistor. In the color filter substrate, a black matrix, a color filter, and a common electrode are sequentially formed on a glass substrate. The common electrode is continuously and entirely formed in the color filter substrate, and a fixed voltage is applied. Above

rW2805PA 200815801 . The black matrix corresponds to the scan line, data line and thin film transistor settings. The direction of alignment of the liquid crystal molecules of the liquid crystal layer is rotated by the cross-pressure between the common electrode and the halogen electrode. However, when ink jets are ejected by ink jet printing at a plurality of openings of the black matrix to form color filters of different colors, the black matrix is caused by the high diffusion ability of the color ink droplets. Color ink droplets of different colors at adjacent openings are prone to overflow outside the opening. Therefore, the problem that color ink droplets of different colors are mixed with each other between adjacent openings of the black matrix 10 is seriously affected, which seriously affects the color purity and contrast of the color filter. As a result, the practicality of the liquid crystal display panel will be greatly reduced. [Summary of the Invention]

In view of the above, an object of the present invention is to provide a color filter substrate, a method of manufacturing the same, and a liquid crystal display panel using the same. The design of different surface characteristics inside and outside the opening of the black matrix enables the color ink droplets of different colors to be more easily concentrated when inkjet printing is sprayed into the opening of the black matrix to form color filters of different colors. The opening of the black matrix. Therefore, it is possible to avoid not only the phenomenon that the color inks of different colors at the adjacent openings of the black matrix overflow to the outside of the opening, but also to solve the problem that the color ink droplets of different colors are traditionally generated between the adjacent opening σ of the black matrix.
