Problems solved by technology

However, in the production method described in Patent Document 1, there is a problem that the thickness of each colored portion formed is uneven.
If such a problem occurs, color unevenness and density unevenness will occur in various parts of the colored part, and as a result, color unevenness and density unevenness will occur in various parts of the color filter.
In addition, unevenness in characteristics (especially color characteristics such as contrast ratio and color reproduction area) occurs among a plurality of color filters manufactured, and the reliability of the color filter is low.
Especially when manufacturing color filters for large-scale liquid crystal display devices, such problems are more obvious

Embodiment 1

[0209] First, resin a as a resin material was synthesized as follows.

[0210] After putting n-hexane: 320 parts by weight, methacrylic acid: 86 parts by weight, and triethylamine: 111 parts by weight into the 4-necked flask, a thermometer, a reflux cooler, a stirrer, and a nitrogen inlet were installed in the 4-necked flask. The 4-necked flask was cooled with ice water, and trimethylchlorosilane: 120 parts by weight was dripped at the same time. At this time, the temperature in the reaction system was controlled to be 25° C. or lower. Then, the reaction was continued at 25°C for 1 hour. Next, the hydrochloride of triethylamine was filtered off, n-hexane was removed from the obtained liquid under reduced pressure, and then purified by distillation under reduced pressure to obtain an ethylenically unsaturated monomer having a silyl acetate structure .

[0211] Next, a thermometer, a reflux cooler, a stirrer, and a nitrogen inlet were installed, and a 4-necked flask was charg...

Embodiment 2～10

[0217] Except for the types of liquid media shown in the table and the usage-amounts of the components shown in the table, the color filter ink (ink set) was prepared in the same manner as in Example 1 above. However, when the composition of the liquid medium is changed, at the same time, the solvent-synthesized resin a with the changed composition is used, and the solution of the resin a thus synthesized is used for preparation of the color filter ink.

Abstract

The invention provides a ink used for manufacturing the color filter which has no uneven color or no uneven density. Further, the ink can also be used for manufacturing the color filter which has excellent uniformity of characteristics among the manufactured color filters. A color filter which has no uneven color or no uneven density and has excellent uniformity of characteristics among the manufactured color filters is also provided. A method of manufacturing such a color filter is also provided. An image display apparatus that can suitably use such a color filter is also provided. An electronic apparatus that can suitably use such an image display apparatus is also provided. The ink comprises a coloring agent and a liquid medium, wherein the liquid medium comprising a component a and a component b, wherein a boiling point of the component B is higher than a boiling point of the component A, and a viscosity of the component B at a temperature of 25 DEG C.

Description

technical field [0001] The present invention relates to an ink for a color filter, a color filter, a manufacturing method of the color filter, an image display device and an electronic instrument. Background technique [0002] Color filters are generally used in liquid crystal display devices (LCD) and the like that perform color display. [0003] In the past, color filters were manufactured using the so-called photolithography method, that is, a material (composition for forming a colored layer) composed of a colorant, a photosensitive resin, a functional monomer, a polymerization initiator, etc. was formed on a substrate. The coating film is then subjected to photosensitive treatment by irradiating light through a photomask, development treatment, and the like. In such a method, a coating film corresponding to each color is usually formed on almost the entire surface of the substrate, and only a part is cured, and most of the other parts are removed, and this operation is...
