Problems solved by technology

When parts are replaced or repaired, it is necessary to adjust the droplet discharge conditions (for example, voltage waveform, etc.) in order to suppress the characteristic deviation among the manufactured multiple color filters, which is also a major cause of the decrease in the productivity of color filters. reason

Embodiment 1

[0168] First, resin a as a resin material was synthesized as follows.

[0169] After putting n-hexane: 320% by weight, methacrylic acid: 86% by weight, and triethylamine: 111% by weight into the four-necked flask, a thermometer, a condensation reflux device, a stirrer and a nitrogen inlet were installed in the four-necked flask. The four-neck flask was cooled with ice water, and trimethylchlorosilane: 120% by weight was refluxed. At this time, the temperature in the reaction system was set to 25° C. or lower. Then, it was reacted at 25° C. for 1 hour. Next, the hydrochloride of triethylamine was separated by filtration, n-hexane was removed from the obtained filtrate under reduced pressure, and then purified by distillation under reduced pressure to obtain ethylenic non-hydrochloric acid having a silyl acetate structure. saturated monomer.

[0170] Then, a thermometer, a condensing reflux device, a stirrer and a nitrogen inlet were installed, and four four-neck flasks fille...

Embodiment 2～13

[0175] Inks for color filters (ink cartridges) were prepared in the same manner as in the above-mentioned Examples except that the types of liquid media and the usage-amounts of the components were as shown in the table. In addition, when the composition of the liquid medium is changed, the resin a is synthesized by using a solvent whose composition is changed accordingly, and a solution of the resin a thus synthesized is used to prepare the color filter ink.

Abstract

The invention provides a color filter which is able to restrain the hue unevenness and concentration unevenness of each part, and has excellent homogeneity of the characteristics between the individuals, and ink for color filter which is well suitable for manufacturing the color filter manufactured based on the inkjet method, image display device comprising the color filter and electronic apparatus. The ink for color filter for manufacturing a color filter with an ink-jet method includes a colorant and a liquid medium into which the colorant is dissolved and / or dispersed. The liquid medium includes an alkoxyl group and an acetyl group at both ends of a molecular chain and at least one ether oxygen atom within a molecule; when a hardened butyl rubber is sealed inside the liquid medium for 10 days under atmospheric pressure at 40 DEG C., a swelling ratio of the hardened butyl rubber is not higher than 20%.

Description

technical field [0001] The present invention relates to an ink for color filters, a color filter, an image display device, and electronic equipment. Background technique [0002] Color filters are generally used in liquid crystal display devices (LCD) and the like that perform color display. [0003] Conventionally, for color filters, a coating film composed of a material (a composition for forming a colored layer) containing a colorant, a photosensitive resin, a functional monomer, a polymerization initiator, etc. The photosensitive treatment and development treatment of the photomask irradiated with light are commonly referred to as photolithography (photolithography) manufacturing. In this method, generally, coating films corresponding to various colors are formed on almost the entire substrate, and only a part of them is cured and the remaining part is removed repeatedly, thereby avoiding overlapping of various colors to produce a color filter. Therefore, only a part o...
