Problems solved by technology
Because the thickness of the black matrix is thin, and the flatness of the surface of the traditional carbon black resin material is not good after exposure and development, when the color filter is manufactured by the inkjet method, the ink is easier to wet the uneven surface, so adjacent The color ink is prone to color mixing
A common solution is to form a barrier layer on the traditional black matrix, but in this way, the process becomes complicated, and the advantages of the simple process of the inkjet method cannot be fully realized

The invention provides a color filter and a method for producing the same, which belong to the field of liquid crystal displays. The color filter comprises a glass substrate, a black matrix and a retaining wall which are simultaneously formed on the glass substrate through a single exposure and development technology, and a plurality of color filter units which are formed in a plurality of sub-pixel areas in an ink jet manner. By the embodiment of the invention, the processing technology for producing the color filter can be simplified in the ink jet manner. The technical scheme provided by the invention is suitable for the production technology of the color filter.
Description
technical field [0001] The invention relates to the field of liquid crystal displays, in particular to a color filter and a manufacturing method thereof. Background technique [0002] Since the liquid crystal display (Liquid Crystal Display, LCD) is a non-active light-emitting component, it must provide light through the internal backlight, and cooperate with the driver IC and liquid crystal control to form black and white grayscale display, and then pass through the color filter The red (R), green (G), and blue (B) color layers of the color filter (CF) form a color display screen, so the color filter is a key component of the colorization of the liquid crystal display. [0003] The process of preparing the color filter by the inkjet method is mainly to use an inkjet device to spray the ink containing the RGB color layer on the black matrix of the transparent substrate at the same time, and the ink droplets are solidified with the solvent volatilization to form a pixel filte...
