Description

Method for manufacturing color filter, color filter, and liquid crystal display device The present invention relates to a method for manufacturing a filter, a filter, and a liquid crystal display device, and particularly to a method for manufacturing a color filter, a color filter, and a liquid crystal display device. Examples of color display devices using color filters include (i) color liquid crystal display devices, which include a combination of a backlight as a light source, liquid crystal as an optical shutter, and a color filter having a color adjustment function (such as a color conversion function, a color separation function, and a color correction function); and (ii) color organic electroluminescence (EL) display devices, which include a combination of a synthesized white organic electroluminescence (EL) light source and a color filter having a color adjustment function (such as a color conversion function, a color separation function, and a color correction function). Color filters can also be used in image sensors such as complementary metal-oxide-semiconductor (CMOS) and charge-coupled device (CCD). Currently, known methods for manufacturing color filters include the electro-deposition method, the printing method, and the photolithography method. In the electro-deposition method, a transparent electrode with a specified pattern is formed in advance; by applying a voltage, the resin containing pigments dissolved or dispersed in a solvent is ionized to form a pattern. The printing method uses printing methods such as offset printing with an ink containing a thermosetting resin or an ultraviolet-curable resin. The photolithography method uses a photosensitive coloring resin composition in which a coloring agent such as a pigment or a dye is dispersed or dissolved in a photoresist material. In recent years, the photolithography method has been the mainstream method for manufacturing color filters. When forming a color filter using the photolithography method, for example, after forming a coating film of a negative-type photosensitive coloring resin composition on a substrate, ultraviolet exposure is performed on the coating film through a photomask having a specified opening pattern, and then, the unexposed portion is dissolved and removed by development to form a pattern (for example: Patent Document 1). However, although various methods for manufacturing color filters have been developed currently, the coloring layer (pattern) in the color filter formed by the photosensitive coloring resin composition has the disadvantage of poor post-baking residue film rate, and a relatively large amount of the photosensitive coloring resin composition is required to produce the coloring layer (pattern), thus failing to achieve the effects of saving resource usage and being environmentally friendly. [Patent Document] [Patent Document 1] JP H2-144502-A Therefore, how to improve the post-baking residual film rate of the coloring layer (pattern) in the color filter formed by the photosensitive coloring resin composition is indeed an urgent problem to be solved by those skilled in the art in this field at present. The present invention provides a method for manufacturing a color filter, a color filter, and a liquid crystal display device, in which the coloring layer (pattern) in the color filter manufactured by the method for manufacturing a color filter has a good post-baking residual film rate.

To make the above features and advantages of the present invention more obvious and understandable, specific embodiments are given below and described in detail as follows. < Color Filter and Method for Manufacturing the Same > This embodiment provides a color filter which is made by the method for manufacturing a color filter as described below. In the method for manufacturing the color filter of this embodiment, by limiting the pigment (A) in the photosensitive coloring resin composition to include a compound represented by formula (1) as the pigment (A-1), and limiting the post-baking temperature to 120°C to 180°C, the post-baking residual film rate of the coloring layer (pattern) in the color filter can be made good, so that the coloring layer (pattern) can be made with a relatively small amount of the photosensitive coloring resin composition, thereby achieving the effects of saving resource use and being environmentally friendly. The following will detail steps (i) to (iv) with the lithography process method as the main axis in the method for manufacturing a color filter: Step (i): Coating a photosensitive coloring resin composition on a substrate to obtain a coating film; Step (ii): Exposing the coating film with ultraviolet light through a photomask; Step (iii): Developing the exposed coating film with a developer to obtain a pattern; and Step (iv): Post-baking the pattern in a temperature range of 120°C to 180°C to obtain the coloring layer of the color filter. Step ( i ) Step (i) is to coat a photosensitive coloring resin composition on a substrate to obtain a coating film. The photosensitive coloring resin composition in step (i) will be described in detail later. The substrate in step (i) is not particularly limited, and examples include transparent substrates. Specific examples of the transparent substrate include glass substrates such as soda-lime glass, low-alkali borosilicate glass, and non-alkali aluminoborosilicate glass with high transmittance to visible light; and plastic substrates such as polycarbonate, polymethyl methacrylate, polyethylene terephthalate, and polyethylene naphthalate. Also, the above substrate can be appropriately pre-treated according to requirements. The pre-treatment examples include chemical treatment such as silane coupling agent, plasma treatment, ion plating, sputtering, gas phase reaction method, vacuum evaporation, or a combination thereof. In addition, in order to drive the liquid crystal to emit light after panelization, a transparent electrode made of indium oxide and / or tin oxide can be formed on the surface of a glass substrate or a plastic substrate. In addition, when a color filter is applied to a liquid crystal display device, the contrast can be further improved by forming a black matrix in advance. Examples of the black matrix include, but are not limited to, an inorganic film such as a chromium or chromium / chromium oxide multilayer film, titanium nitride, or a resin film in which a light-shielding agent is dispersed. The coating method in step (i) is not particularly limited, and examples thereof include coating the photosensitive coloring resin composition on a substrate by a coating method such as spraying, spin coating, slit coating, roll coating, or a combination thereof to obtain a coating film. In addition, after the photosensitive coloring resin composition is coated on the substrate, drying under reduced pressure or pre-baking can be performed as needed to volatilize the solvent. Among them, the conditions for drying under reduced pressure and pre-baking are not particularly limited and can be adjusted according to the types and compounding ratios of the respective components. Generally, drying under reduced pressure is performed at a pressure of 0 to 200 mmHg for 1 second to 60 seconds, and pre-baking is performed at a temperature of 70 to 110 °C for 1 minute to 15 minutes. Step ( ii ) Step (ii) is to perform an exposure treatment on the coating film with ultraviolet rays隔着 a photomask. The light used for exposure is preferably ultraviolet rays such as g-line, h-line, and i-line, and the ultraviolet ray device can be a (super) high-pressure mercury lamp or a metal halide lamp. The exposure amount of ultraviolet rays is not particularly limited, but is preferably 1 to 1000 mJ / cm 2 . Step ( iii ) Step (iii) is to perform a development treatment on the exposed coating film with a developer to obtain a pattern. The developer used in the development treatment is not particularly limited, and examples thereof include an alkaline developer. The alkaline developer is not particularly limited, and examples thereof include aqueous solutions of sodium carbonate, sodium hydroxide, etc., and organic bases such as dimethylbenzylamine and triethanolamine can also be used. In addition, an antifoaming agent, a surfactant, or a combination thereof can be added to the developer. The method of the development treatment is not particularly limited, and examples thereof include forming by dissolving and removing the unexposed portion of the coating film by a method such as a spray development method, a spray development method, a dip development method, a puddle development method, etc. Step ( iv ) Step (iv) is to perform post-baking treatment on the pattern in the temperature range of 120°C to 180°C to obtain a colored layer (color filter). It should be noted that when the post-baking temperature is lower than 120°C or higher than 180°C, the post-baking residual film rate of the pattern made of the photosensitive coloring resin composition is not good. In addition, the post-baking treatment is preferably carried out in the temperature range of 150°C to 180°C. When the post-baking temperature is in the range of 150°C to 180°C and the photosensitive coloring resin composition contains the pigment (A-1), the pattern produced has a better post-baking residual film rate. The time of the post-baking treatment is not particularly limited. For example, it is 5 minutes to 120 minutes, preferably 10 minutes to 90 minutes, and more preferably 15 minutes to 60 minutes. In addition, the heating device for the post-baking treatment is not particularly limited, and heating devices such as a hot plate or an oven can be cited. On the other hand, the above steps (i) to (iv) do not necessarily need to be carried out continuously, and other steps can be inserted in each step as needed. For example, after step (i), a water-soluble resin or an alkali-soluble resin such as polyvinyl alcohol or a water-soluble acrylic resin is coated on the coating film and dried to increase the ultraviolet exposure sensitivity, and then a film for preventing oxygen inhibition of polymerization is formed and then step (ii) is carried out. In addition, after step (iii), the pattern can be further exposed to ultraviolet rays to promote the photocrosslinking reaction and then step (iv) is carried out. The color filter obtained by the manufacturing method of the color filter of this embodiment can be applied to but not limited to liquid crystal display devices, etc. < Liquid Crystal Display Device and Its Manufacturing Method > This embodiment provides a liquid crystal display device, which may include a color filter obtained by the manufacturing method of the above color filter.

After stirring evenly with a shaking type stirrer, the photosensitive coloring resin composition of Example 1 can be manufactured. b. Fabrication of Pattern (Coloring Layer for Color Filter) The photosensitive coloring resin composition of Example 1 was spin-coated on a 100 mm × 100 mm glass substrate. First, it was dried under reduced pressure at a pressure of 100 mmHg for 30 seconds, and then pre-baked at a temperature of 90 °C for 2 minutes to form a pre-baked coating film with a film thickness of 1.2 μm. Then, the pre-baked coating film was irradiated with ultraviolet light (exposure machine Canon PLA-501F) at a light quantity of 100 mJ / cm 2 After that, it was immersed in a developer at 23 °C for 1 minute, washed with pure water, and then post-baked at 120 °C for 30 minutes to form a pattern (coloring layer for color filter) with a film thickness of 1.0 μm on the glass substrate. The pattern of Experimental Example 1 obtained was evaluated by the evaluation method described below, and the results are shown in Table 1. Experimental Example 2 to Experimental Example 11 , Comparative Example 1 to Comparative Example 4 The photosensitive colored resin compositions and colored layers (color filters) of Experimental Examples 2 to 21 and Comparative Examples 1 to 4 were prepared in the same steps as Experimental Example 1, and the differences were as follows: the types and amounts of components of the photosensitive colored resin composition and the range of post-baking temperature were changed. Among them, Experimental Examples 2 to 21 are shown in Table 1, and Comparative Examples 1 to 4 are shown in Table 2). The components corresponding to the labels in Table 1 and Table 2 are shown in Table 3. The photosensitive colored resin compositions obtained were evaluated by the evaluation method described below, and the results of Experimental Examples 2 to 21 and Comparative Examples 1 to 4 are shown in Table 1 and Table 2, respectively. Table 1 Table 1 (continued) Table 2 Table 3 [ Evaluation method ] Post-baking residual film rate For the formed pattern, a film thickness measuring device (DEKTAK3; manufactured by Nippon Vacuum Technology Co., Ltd.) was used to measure the film thickness before and after post-baking, and the post-baking residual film rate was calculated according to the following formula. The results are shown in Table 1 and Table 2. Post-baking residual film rate (%) = (film thickness after post-baking / film thickness before post-baking) × 100 (%) A large numerical value indicates a high residual film rate after post-baking and good results. If the residual film rate is high, adverse situations such as cracks or haze caused by film shrinkage during heating are less likely to occur. ※: Post-baking residual film rate > 98%. ◎: 98% ≥ Post-baking residual film rate > 95%. ○: 95% ≥ Post-baking residual film rate > 93%. △: 93% ≥ Post-baking residual film rate > 90%. ╳: Post-baking residual film rate ≤ 90%. < Evaluation results > As can be seen from Table 1 and Table 2, compared with the colored layer produced when the post-baking temperature is not in the range of 120°C to 180°C and / or the photosensitive coloring resin composition does not contain the pigment (A-1), under the conditions that the post-baking temperature is in the range of 120°C to 180°C and the photosensitive coloring resin composition contains the pigment (A-1), the pattern (colored layer) produced by the photosensitive coloring resin composition has a good post-baking residual film rate. Among them, when the post-baking temperature is lower than 120°C or higher than 180°C, the post-baking residual film rate of the pattern produced by the photosensitive coloring resin composition is not good. In addition, when the photosensitive coloring resin composition does not contain the pigment (A-1), the post-baking residual film rate of the pattern produced by the photosensitive coloring resin composition is not good. When the photosensitive coloring resin composition contains the pigment (A-1) corresponding to R in formula (1) 2 、R 3 、R 4 、and R 5 each independently represents a substituted or unsubstituted alkyl group, the pattern produced by the photosensitive coloring resin composition has a better post-baking residual film rate. When the post-baking temperature is in the range of 150°C to 180°C and the photosensitive coloring resin composition contains the pigment (A-1), the pattern produced has a better post-baking residual film rate. When the photosensitive coloring resin composition further includes the dye (B-1), the pattern produced by the photosensitive coloring resin composition has a better post-baking residual film rate. In summary, the present invention provides a method for manufacturing a color filter, and the photosensitive coloring resin composition used therein includes a compound represented by formula (1) as the pigment (A-1) and performs post-baking treatment on the pattern in the temperature range of 120°C to 180°C, so that the colored layer (pattern) in the color filter has a good post-baking residual film rate, thereby avoiding problems such as color mixing and pattern dissolution; at the same time, the colored layer (pattern) can also be made with a relatively small amount of the photosensitive coloring resin composition, so as to achieve the effects of saving resource use and being environmentally friendly. Although the present invention has been disclosed as above with embodiments, it is not intended to limit the present invention. Any person with ordinary knowledge in the technical field can make some changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be determined by the scope of the appended patent application. None None
