Problems solved by technology

[0006] However, in this type of ink-jet manufacturing of color filters, in order to avoid the ink between the black matrices before being cured, the colors will be mixed with each other, and there is a problem that it is difficult to reproduce bright colors. Therefore, when ink-jet It will control the volume injected by the micro-liquid to not exceed the height of the black matrix, so that the color layer 17 is formed as Figure 1F As shown, the color layer 17 forms a slightly convex shape and gaps 171 are formed between the two sides and the black matrix 121, which will interfere with the normal operation of the liquid crystal display device and cannot present the ideal color combination.

Embodiment Construction

[0021] In order to make your examiner clear the main technical content and implementation of the present invention, the following descriptions are provided in conjunction with the drawings:

[0022] The inkjet ink of the present invention is basically composed of polymer resin (Resin), pigment (Pigment), photo initiator (Photo initiator), monomer (Monomer), three solvents with different boiling points (Solvent) and additives (Additives). ) Is an inkjet ink suitable for color filters, and the viscosity of the inkjet ink is about 10-25 mPa.s, and the solid content is about 20% to 35% by weight; where:

[0023] The function of polymer resin (Resin) lies in adhesion, developability, pigment dispersibility, fluidity, heat resistance, chemical resistance, and analytical ability; the function of pigment (Pigment) lies in coloring and colorization; photosensitive initiator ( The function of Photo initiator lies in the photosensitive properties and analytical ability; the function of Monome...

Abstract

The invention relates to ink-jet ink for a color filter, containing high-molecular resin, paint, a photosensitive starting agent, a monomer, three solvents with different boiling points and an additive, wherein the viscosity of the ink-jet ink is about 10-25 mPa. s, and the solid content of the ink-jet ink is about 20 percent to 35 percent by weight, thereby the ink-jet ink with a developing function is formed.

Description

Technical field [0001] The present invention improves the composition of inkjet ink, and aims to provide an inkjet ink suitable for color filters and having a developing function. Background technique [0002] Generally speaking, the main components of a liquid crystal display device are composed of two electrode substrates each having pixels (pixels) formed by electrodes that are arranged opposite to each other, arranged opposite each other with a gap, and are sealed and sandwiched around the gap. The liquid crystal layer is formed. In liquid crystal display devices, especially liquid crystal display devices that can display arbitrary color images, color filters are generally used. The color filters are provided with R, G, B (red) on either of the two electrode substrates. , Green, and blue) or the arrangement of colorable multi-color hue dyeing elements corresponding to each pixel. [0003] In the manufacturing method of color filters, there are a pigment dispersion method in w...
