2. Description of the Related Art It is known that a recording device such as an ink jet recording device applies ink of a predetermined color to each pixel formed by partitioning a bank on a substrate. Generally, three color inks of red, green, and blue are applied to a color filter in a predetermined arrangement, and these three colors of red, green, and blue are specifically determined depending on a difference in a target to which the color filter is used.

FIG. 4A is a plan view, and FIG. 4B is a sectional view taken along line BB ′ of FIG. 4A. The hatching of each part of the sectional view is partially omitted.

As shown in FIG. 4A, the color filter 200 includes pixels 13 arranged in a matrix.
The boundary between the pixels is separated by a partition 14. Any one of red (R), green (G), and blue (B) ink is introduced into each of the pixels 13. In this example, the arrangement of red, green, and blue is a so-called mosaic arrangement,
Other arrangements such as a stripe arrangement and a delta arrangement may be used.

As shown in FIG. 4B, the color filter 200 includes a light-transmitting substrate 12 and a light-shielding partition 1.
4 is provided. The portion where the partition 14 is not formed (removed) forms the pixel 13. The ink of each color introduced into the pixel 13 forms the colored layer 20. On the upper surfaces of the partition 14 and the colored layer 20, an overcoat layer 21 and an electrode layer 22 are formed.

(5. Method for manufacturing color filter (1))
FIG. 5 is a cross-sectional view showing a manufacturing process for explaining the method for manufacturing the color filter according to the first embodiment. The hatching of each part of the sectional view is partially omitted.

(5-1. Bank Formation and Surface Treatment Step)
The surface of the transparent substrate 12 made of non-alkali glass having a thickness of 0.7 mm, a length of 38 cm and a width of 30 cm is washed with a cleaning solution obtained by adding 1% by weight of hydrogen peroxide to hot concentrated sulfuric acid, and rinsed with pure water. Perform air drying to obtain a clean surface. On this surface, a chromium film is formed with an average thickness of 0.2 μm by sputtering to obtain a metal layer 16 ′ (FIG. 5: S1).

After the substrate is dried on a hot plate at 80 ° C. for 5 minutes, a photoresist layer (not shown) is formed on the surface of the metal layer 16 ′ by spin coating.
A mask film on which a required matrix pattern shape is drawn is brought into close contact with the substrate surface, and exposure is performed with ultraviolet light. Next, this is immersed in an alkali developing solution containing potassium hydroxide at a ratio of 8% by weight to remove an unexposed portion of the photoresist and pattern the resist layer. Subsequently, the exposed metal layer is removed by etching with an etching solution containing hydrochloric acid as a main component. Light shielding layer (black matrix) having a predetermined matrix pattern in this way
16 can be obtained (FIG. 5: S2). The thickness of the light shielding layer 16 is approximately 0.2 μm. Further, the width of the light shielding layer 16 is about 22 μm.

On this substrate, a negative type transparent acrylic photosensitive resin composition 17 'is further applied by a spin coating method (FIG. 5: S3). After pre-baking at 100 ° C. for 20 minutes, UV exposure is performed using a mask film on which a predetermined matrix pattern shape is drawn. The unexposed portion of the resin is also developed with an alkaline developer, rinsed with pure water, and then spin-dried. After-baking as final drying is performed at 200 ° C. for 30 minutes to sufficiently cure the resin portion, thereby forming the bank layer 17 and the partition 14 including the light shielding layer 16 and the bank layer 17 is formed (FIG. 5: S4). ). The bank layer 17 has an average thickness of 2.7 μm. The width of the bank layer 17 is about 14 μm.

In order to improve the ink wettability of the obtained colored layer forming region (particularly the exposed surface of the glass substrate 12) partitioned by the light shielding layer 16 and the bank layer 17, dry etching, that is, atmospheric pressure plasma treatment is performed. Specifically, a high voltage is applied to a mixed gas of helium and oxygen at 20%, a plasma atmosphere is formed in an etching spot at atmospheric pressure, and the substrate is etched by passing under the etching spot.

(5-2. Ink Introducing Step) Next, in the pixel 13 formed by being partitioned by the partition 14, the first
Each of the (red), second (green), and third (blue) inks is introduced by an inkjet method (FIG. 5: S5). For the inkjet head, use a precision head that applies the piezo piezoelectric effect.
Selectively skip. The drive frequency is set to 14.4 kHz, that is, the ejection interval of each ink droplet is set to 69.5 μsec.
The distance between the head and the target is set to 0.3 mm. In order to prevent the flying speed from the head to the target colored layer forming region, the bending of the flight, and the generation of split stray droplets called satellites, not only the physical properties of the ink but also the waveform (including the voltage) driving the piezoelectric element of the head. )is important. Therefore, a waveform whose conditions are set in advance is programmed, and ink droplets are simultaneously applied to three colors of red, green, and blue, and ink is applied to a predetermined coloration pattern.

As the ink, for example, after dispersing an inorganic pigment in a polyurethane resin oligomer, cyclohexanone and butyl acetate are added as low-boiling solvents, and butyl carbitol acetate is added as a high-boiling solvent. A solution having a viscosity of 6 to 8 centipoise by adding 01% by weight as a dispersant is used.

(5-3. Drying / Curing Step) Next, the applied ink is dried. First, the ink layer 19 was set by leaving the ink layer 19 in a natural atmosphere for 3 hours.
Then, the ink layer 19 is cured by heating at 200 ° C. for 30 minutes in an oven to obtain a colored layer 20 (FIG. 5: S6).

A transparent acrylic resin paint is spin-coated on the substrate to form an overcoat layer 21 having a smooth surface. Furthermore, ITO (Indium Tin Oxid
The electrode layer 22 of e) is formed in a required pattern to form a color filter 200 (FIG. 5: S7).

(6. Method for manufacturing color filter (2))
FIG. 6 is a manufacturing process sectional view for explaining the method for manufacturing the color filter according to the second embodiment. The same steps as those in the manufacturing method according to the first embodiment are denoted by the same reference numerals, and description thereof is omitted.

The difference between the second embodiment and the first embodiment is that the ink application step (S5a, S5b)
The point is that each of the inks of the color a and the color b, which constitute the color to be applied to the pixel by the subtractive color mixture, is applied by different ink jet heads (ink applying units).

Specifically, for example, magenta,
Each color of yellow is applied to one pixel as a color b to form a red color layer, and similarly, each color of cyan and yellow is applied to another pixel to form a green color layer. Each magenta ink is further applied to another pixel to form a blue colored layer.

In the second embodiment, the same recording apparatus as that shown in FIG. 1 can be used for applying ink to the color filter substrate. The ink flow path from the ink tank to the ink jet head is different from that in FIG. 2, and is different from the cyan ink tank to the cyan ink jet head, the magenta ink tank to the magenta ink jet head, and the yellow ink tank to the yellow ink tank. The ink is supplied directly to the inkjet heads.

The structure of the control system of the printing apparatus is described in FIG.
Almost the same can be used. However, the difference is that the mixing of the raw materials is not performed in the mixing section 33.
In addition, the control of the mixing ratio of the ink in the mixing unit 33 may be performed by a valve or a pump, or may be performed by a driving voltage for the inkjet head or the number of ejection dots per pixel.

As shown in FIG. 6, by applying the ink 19a of the color a (S5a) and immediately applying the ink 19b of the color b (S5b), the ink can be mixed in the pixel. In this case, it is desirable that the solvent of the ink be low in volatility so that both inks are sufficiently mixed. Alternatively, the raw material inks may be alternately applied to the same pixel, such as color a → color b → color a → color b, to facilitate mixing.

However, the present invention is not limited to this. After the color a ink is applied, the color a ink is dried and cured if necessary, and then the color b ink is applied. The colored layer b may be formed in two layers. According to this, it is possible to make the distribution in the pixels uniform without worrying about the degree of mixing of the two inks.

According to the present embodiment, ink of the same color always flows in the ink flow path and a desired color is formed in the pixel. Therefore, even when the color to be formed in the pixel is changed, the flow path is not changed. No need to wash.
