Colour filter and its manufacture method

The colour filter of the present invention possesses the dyed layer containing specific coloring compound.

As the method for manufacture colour filter, first can enumerate following methods.First, on the surface of the substrate, as needed, press Light shield layer (black matrix) is formed according to the mode for marking off the part to form pixel.Then, on the substrate, coating is for example containing spy After the liquid composition of blue radiation-ray sensitive composition for determining coloring compound, carrying out prebake conditions evaporates solvent, is formed Film.Then, after being exposed via photomask to the film, developed using alkaline-based developer, dissolving removes not exposing for film Light portion.Afterwards, by rear baking, form blue pixel patterns to provide the pel array being arranged.

Then, using green or red each colored radiation-sensitive composition, as described above, each coloring is carried out Coating, prebake conditions, exposure, development and the rear baking of radiation-ray sensitive composition, are sequentially formed green picture on the same substrate Pixel array and red pixel array.Thus, obtain being configured with red, green and blue trichromatic pel array on substrate Colour filter.But, in the present invention, the order for forming each color pixel is not limited to said sequence.

In addition, black matrix can be by using photoetching process by by sputtering or evaporation, the metallic film such as chromium of film forming is made Desired pattern can also use the colored radiation-sensitive composition and above-mentioned picture for being dispersed with black colorant to be formed The situation that element is formed is identically formed.The coloured composition of the present invention can also perform well in the formation of the black matrix.

As the substrate used when forming colour filter, for example, it can enumerate glass, silicon, makrolon, polyester, aromatic series polyamides Amine, polyamidoimide, polyimides etc..

In addition, to these substrates, as needed, can also implement in advance agent treatment using silane coupler etc., etc. The appropriate pre-treatments such as gas ions processing, ion plating, sputtering, gas-phase reaction method, vacuum evaporation.

When colored radiation-sensitive composition is applied on substrate, spraying process, rolling method, rotary coating can be used The appropriate rubbing methods such as method (spin-coating method), slot die coating method, stick coating method, are particularly preferably applied using spin-coating method, slot die Cloth method.

Prebake conditions will generally be dried under reduced pressure to combine with heat drying and carry out.It is dried under reduced pressure and generally proceeds to 50~200Pa.Separately Outside, the condition of heat drying is typically 70~110 DEG C, 1~10 minute or so.

Coating thickness is with dried film thickness gauge, preferably typically 0.6~8.0 μm, 1.2~5.0 μm.

As the light source of the radioactive ray used when forming pixel and/or black matrix, for example, it can enumerate xenon lamp, Halogen lamp LED, tungsten The lamp sources, argon ion such as lamp, high-pressure mercury-vapor lamp, extra-high-pressure mercury vapour lamp, metal halide lamp, middle medium pressure mercury lamp, Cooper-Hewitt lamp Laser light sources such as laser, YAG laser, XeCl quasi-molecule laser, nitrogen laser etc., but optimal wavelength 190~ The radioactive ray of 450nm scopes.

The light exposure of radioactive ray generally preferably 10~10000J/m²。

In addition, being used as above-mentioned alkaline-based developer, such as preferred sodium carbonate, sodium hydroxide, potassium hydroxide, tetramethyl hydroxide Ammonium, choline, 1,8- diazabicyclos [5.4.0] -7- endecatylenes, 1,5- diazabicyclos [4.3.0] -5- nonenes etc. it is water-soluble Liquid.

In above-mentioned alkaline-based developer, the water-miscible organic solvent such as methanol, ethanol, surface can also be added in right amount and is lived Property agent etc..It should illustrate, generally be washed after alkaline development.

As development treatment method, applicable spray development method, spray development method, dipping (dip) development method, leaching are put (submergence) Development method etc..Development conditions are preferably under normal temperature 5~300 seconds.

The condition toasted afterwards is typically 120~280 DEG C, 10~60 minutes or so, is examined in terms of the heat resistance in line with toner Consider, the temperature toasted afterwards is preferably below 240 DEG C, particularly preferably below 230 DEG C.

The thickness of the pixel so formed is typically 0.5~5.0 μm, preferably 1.0~3.0 μm.

In addition, as the second method of manufacture colour filter, Japanese Unexamined Patent Publication 7-318723 publications, Japanese Unexamined Patent Publication can be used The method that utilization ink-jetting style disclosed in 2000-310706 publications etc. obtains the pixel of colors.In the method, first, The next door for having shade function concurrently is formed on the surface of the substrate.Then, in the next door of formation, by ink discharge device will for example containing The liquid composition of the blue colored composition of specific coloring compound sprays, and then carrying out prebake conditions evaporates solvent.Then, After the film is exposed as needed, toasted after progress, thus solidify it, form blue pixel patterns.

Then, using green or red each coloured composition, as described above, it is sequentially formed on the same substrate green Color pixel pattern and red pixel pattern.Thus, obtain being configured with red, green and blue trichromatic pixel map on substrate The colour filter of case.But, in the present invention, the order for forming each color pixel is not limited to said sequence.

It should illustrate, above-mentioned next door not only acts as shade function, also act as each chromatic colorant made to be ejected into zoning The function of composition not colour mixture, thus the black matrix used in the above-mentioned first method of Film Thickness Ratio is thick.Therefore, next door is usually using black Color radiation-ray sensitive composition is formed.

Formed colour filter when the substrate, the light source of radioactive ray and the prebake conditions that use, the method toasted afterwards, condition with it is above-mentioned First method is identical.So, the thickness of the pixel formed by ink-jetting style and the height in next door are same degrees.

In the pattern of pixels so obtained, formed as needed after diaphragm, nesa coating is formed by sputtering. Formed after nesa coating, further can also form separator colour filter is made.Separator is sensitive usually using radioactive ray Property composition is formed, and the separator (black separator) with light-proofness can also be made.Now, using being dispersed with black The colored radiation-sensitive composition of toner, coloured composition of the invention can also perform well in being formed the black every Off member.

The colour filter of the invention so obtained, brightness and excitation are high, thus to color liquid crystal display device, colour Image tube elements, color sensor, organic EL display element, Electronic Paper etc. exceedingly useful.
