In addition, as second method of making color filter, disclosed employing ink-jetting style obtains the method for pixel of all kinds in also known Japanese kokai publication hei 7-318723 communique, the TOHKEMY 2000-310706 communique etc.In the method, at first, on the surface of substrate, form the next door that has shade function concurrently.Then, the fluid composition that will be dispersed with the coloured composition of for example red colorant by ink discharge device carries out prebake conditions and makes solvent evaporation after being ejected in the next door of formation.Then, with this film expose as required after, be cured by back baking, form red pattern of pixels.

Then, use each coloured composition of green or cyan, with the above-mentioned green pattern of pixels and the pattern of pixels of cyan of similarly on same substrate, forming successively.Thus, obtain on substrate, disposing simultaneously the color filter of the trichromatic pattern of pixels of redness, green and cyan.But among the present invention, the order that forms pixel of all kinds is not limited to said sequence.

Have, above-mentioned next door not only has shade function again, also plays to make the not function of colour mixture of the coloured composition of all kinds that is ejected in the subregion, and therefore, the black matrix film thickness that uses in above-mentioned first method is thick.Therefore, the next door uses the black radiation-ray sensitive composition to form usually.

The substrate that uses when forming color filter, the light source of radioactive ray, and method, the condition of prebake conditions, back baking are identical with the first above-mentioned method.Like this, the film thickness of the pixel that forms by ink-jetting style and the thickness of black matrix are same degree.

On the pattern of pixels that obtains like this, form diaphragm as required after, utilize sputter to form nesa coating.After forming nesa coating, can also further form distance piece and form color filter.Distance piece can use radiation-ray sensitive composition to form usually, but also can make the distance piece (spacing body night) with light-proofness.At this moment, use the colored radiation-sensitive composition be dispersed with black colorant, coloured composition of the present invention also can perform well in the formation of this of spacing body night.

The color filter brightness of the present invention and the excitation that obtain like this are high, and be therefore exceedingly useful to color liquid crystal display device, colour pick-up tube element, color sensor, organic EL display element, electronic paper etc.

The evaluation of checkout time

On glass substrate, utilize spin-coating method to be coated with resulting fluid composition after, carry out 2 minutes prebake conditions with 100 ℃ heating plates, forming film thickness is filming of 2.7 μ m.Then, this substrate is cooled to room temperature after, to filming on the substrate, utilize high-pressure sodium lamp to be situated between by photomask with 1 000J/m with the radioactive ray that comprise 365nm, 405nm and each wavelength of 436nm to respectively filming ²Exposure expose.Then, by filming on the substrate sprayed 23 ℃ 0.04 quality % potassium hydroxide aqueous solution, spray development.At this moment, the mensuration unexposed portion films up to the time of peeling off fully (checkout time).And, checkout time is made as " A " less than 60 seconds situation, with being made as " B " more than 60 seconds and less than 120 seconds situation, the situation more than 120 seconds is made as " C ", estimate.This time is short more, and developing powder is fast more, has the advantage of production interval time that can shorten that color filter makes.Evaluation result is shown in table 3.

The evaluation of colorimetric properties

On glass substrate, utilize spin-coating method to be coated with resulting coloured composition after, carry out 2 minutes prebake conditions with 100 ℃ heating plates, form different 3 of film thickness and film.Then, this substrate is cooled to room temperature after, to filming on the substrate, utilize high-pressure sodium lamp not to be situated between by photomask with 1 000J/m with the radioactive ray that comprise 365nm, 405nm and each wavelength of 436nm to respectively filming ²Exposure expose.Then, 220 ℃ of back bakings of carrying out 20 minutes, on substrate, form cured film.To 3 cured film that obtain, with color analyzer (big tomb electronics (strain) system MCPD2000), with illuminant-C, the 2 degree visuals field, measure chromaticity coordinate value in the CIE color specification system (x, y) and values (Y).According to measurement result, chromaticity coordinate value x when obtaining chromaticity coordinate value y=0.590 and values (Y).Evaluation result is shown in table 3.Obtaining the y value for blueness is 0.090 o'clock Y value, x value.
