Problems solved by technology

However, fastness such as light resistance and heat resistance of the color pixel is still insufficient, and it is not necessarily satisfactory for practical use.
[0010] Therefore, there is a problem that it is difficult to cope with recent high-brightness backlights, etc.
[0011] In addition, ITO (Indium Tin Oxide), which is widely used as an electrode of FPD (Flat Panel Display) such as Liquid Crystal Display (LCD), has the problem that the above-mentioned optical characteristics and other characteristics change due to the high temperature during film formation.
[0012] For example, until now, various dye-based inks have been known. As mentioned above, the level of light resistance and heat resistance of color pixels is not sufficient, and further improvement is desired.

Abstract

The invention provides an ink for manufacturing a colour filter having excellent light resistance or heat resistance, a colour filter manufactured by the ink, a manufacturing method of the colour filter and an image display. It is characterized in that the ink comprises a compound represented by formula (1) and a solvent, in which the content of the compound is 1-20 mass percent, the content of the solvent is 30-90 mass percent, and the boiling point of the solvent ranges in 130-280 degrees centigrade; in the formula (1), Za and Zb each independently represent -N=, or -C(R8)=; R1 to R5 and R8 each independently represent a hydrogen atom or a substituting group; R6 and R7 each independently represent a hydrogen atom, alkyl, alkenyl, aryl or heterocyclyl; R2 and R3, R3 and R6, R4 and R5, R5 and R7, and / or R6 and R7 are mutually bondable for independently forming a 5-, 6- or 7-membered ring, respectively.

Description

technical field [0001] The present invention relates to an ink for inkjet, a color filter, a method for producing the same, and a liquid crystal display and an image display device using the color filter. Background technique [0002] In recent years, with the development of personal computers, especially large-screen liquid crystal televisions, the demand for liquid crystal displays (LCDs), especially color liquid crystal displays, tends to increase. However, since color liquid crystal displays are expensive, demands for cost reduction are increasing. In particular, there is a high demand for cost reduction of color filters with a high cost ratio. Such a color filter generally has a coloring pattern of three primary colors of red (R), green (G) and blue (B). In a liquid crystal display provided with this color filter, by turning on and off the electrodes corresponding to each pixel of R, G, and B, the liquid crystal acts as a switch, and light passes through each pixel of...
