Description

Colored curable resin compositions, color filters, display devices, and solid-state imaging devices

本發明是有關於一種著色硬化性樹脂組成物、彩色濾光片、顯示裝置、及固體攝像元件。The present invention relates to a colored curable resin composition, a color filter, a display device, and a solid-state imaging element.

液晶顯示裝置、電致發光（electroluminescence）顯示裝置、及電漿顯示器等顯示裝置或電荷耦合器件（charge coupled device，CCD）或互補性金屬氧化物半導體（complementary metal-oxide semiconductor，CMOS）感測器等固體攝像元件中所使用的彩色濾光片是由著色硬化性樹脂組成物製造。於此種著色硬化性樹脂組成物中使用鹼可溶性樹脂，作為該鹼可溶性樹脂中所使用的單體，例示了具有碳數7左右的芳香族環的單體（專利文獻1）。 [現有技術文獻] [專利文獻] Display devices such as liquid crystal display devices, electroluminescence (electroluminescence) display devices, and plasma displays, or charge coupled device (CCD) or complementary metal-oxide semiconductor (CMOS) sensors Color filters used in solid-state imaging devices such as PTFE are made of colored curable resin compositions. An alkali-soluble resin is used in such a colored curable resin composition. As a monomer used in the alkali-soluble resin, a monomer having an aromatic ring having about 7 carbon atoms is exemplified (Patent Document 1). [Prior art documents] [Patent Document]

[發明所欲解決之課題][Problem to be solved by the invention]

然而，可知若僅由將具有碳數7左右的芳香族環的單體設為單量體的鹼可溶性樹脂構成著色硬化性樹脂組成物，則彩色濾光片的密接性不充分，顯影後的樹脂的線寬變細，因此難以增加著色劑。因此，本發明的課題在於提供一種包含密接性優異、或者對增加著色劑而言有用的樹脂的著色硬化性樹脂組成物。 [解決課題之手段] However, it was found that if the colored curable resin composition is composed only of an alkali-soluble resin containing a monomer having an aromatic ring with about 7 carbon atoms as a monomer, the adhesion of the color filter will not be sufficient, and the result after development will be The line width of the resin becomes thinner, making it difficult to add colorants.

以所述方式獲得的著色圖案及著色塗膜有效用作彩色濾光片。The colored pattern and colored coating film obtained in this manner are effectively used as color filters.

若使用本發明的著色硬化性樹脂組成物，則可使所形成的彩色濾光片的密接性良好。另外，若使用本發明的著色硬化性樹脂組成物，則較佳為可於彩色濾光片的製造中減少顯影時的殘渣的產生。再者，密接性是指形成彩色濾光片時的彩色濾光片與基板等的密接力的強度，若密接性低，則於彩色濾光片產生剝離或缺口的可能性高。於本發明中，彩色濾光片的密接性是利用顯微鏡觀察所獲得的著色圖案（具有點圖案），藉由不剝離而殘存的點的數量進行評價。另外，殘渣是指於使用電子顯微鏡觀察顯影後的著色圖案時（例如，以倍率25000倍觀察），殘存於未曝光部而觀察到的不形成圖案的異物。If the colored curable resin composition of the present invention is used, the formed color filter can have good adhesion. In addition, if the colored curable resin composition of the present invention is used, it is preferable that the generation of residues during development can be reduced in the production of color filters. In addition, adhesion refers to the strength of the adhesion force between the color filter and the substrate when forming the color filter. If the adhesion is low, the possibility of peeling or chipping in the color filter is high. In the present invention, the adhesion of the color filter is evaluated by the number of dots remaining without peeling off the colored pattern (having a dot pattern) obtained by microscopic observation. In addition, the residue refers to foreign matter that remains in the unexposed portion and does not form a pattern when observing the colored pattern after development using an electron microscope (for example, observing at a magnification of 25,000 times).

＜顯示裝置、固體攝像元件＞所述彩色濾光片有效用作顯示裝置（例如，液晶顯示裝置、有機電致發光（electroluminescence，EL）裝置、電子紙等）、及固體攝像元件等中所使用的彩色濾光片。 [實施例] ＜Display devices, solid-state imaging devices＞ The color filter is effectively used as a color filter used in display devices (for example, liquid crystal display devices, organic electroluminescence (EL) devices, electronic paper, etc.), solid-state imaging elements, and the like.

After cooling, the substrate on which the colored composition layer was formed was irradiated with light using an exposure machine (NSR-2205i11D; manufactured by Nikon Co., Ltd.) at an exposure dose of 50 mJ/cm ² (based on 365 nm). During light irradiation, a mask for forming dot patterns of 0.8 μm square and 1.0 μm square (pitches of 1.6 μm and 2.0 μm, respectively) was used. The colored composition layer after light irradiation was immersed and developed in an aqueous developer containing 0.1% tetramethylammonium hydroxide at 23°C for 30 seconds. After washing with water, it was post-baked using a hot plate at 230°C for 10 minutes. , thereby obtaining the post-baked coloring pattern.

（密接性評價）於線寬0.8 μm/線寬1.0 μm的著色圖案中，藉由顯微鏡對於各線寬的著色圖案，觀察亦包括自基板上剝離者在內的100個點，並計數未自基板剝離而殘存的點的個數。按照下述評價基準，對後烘烤後的著色圖案的基板密接性進行評價。將結果示於表8～表10。＜評價基準＞ A：95個～100個 B：71個～94個 C：51個～70個 D：11個～50個 E：0個～10個可以說殘存於基板上的點的數量越多，密接性越良好。 (Tightness evaluation) In the colored pattern with a line width of 0.8 μm/line width of 1.0 μm, use a microscope to observe 100 points of the colored pattern of each line width, including those peeled off from the substrate, and count the remaining points that have not been peeled off from the substrate. number. The substrate adhesion of the colored pattern after post-baking was evaluated based on the following evaluation criteria. The results are shown in Tables 8 to 10. ＜Evaluation Criteria＞ A: 95 to 100 pieces B: 71 to 94 C: 51 to 70 D: 11～50 pieces E: 0 to 10 It can be said that the greater the number of dots remaining on the substrate, the better the adhesion.

由將鹼可溶性樹脂（B-1）及鹼可溶性樹脂（B-2）設為相同量的著色硬化性樹脂組成物形成塗膜時的曝光圖案的線寬評價使用相同量的鹼可溶性樹脂（B-1）與鹼可溶性樹脂（B-2），如以下般形成曝光圖案，並對所獲得的曝光圖案的線寬進行了評價。將其結果示於表11。 Line width evaluation of the exposure pattern when a coating film is formed from a colored curable resin composition in which the alkali-soluble resin (B-1) and the alkali-soluble resin (B-2) are the same amount Using the same amount of alkali-soluble resin (B-1) and alkali-soluble resin (B-2), an exposure pattern was formed as follows, and the line width of the obtained exposure pattern was evaluated. The results are shown in Table 11.

（線寬感度評價）於以曝光量400 mJ/m ²～650 mJ/m ²照射後的線寬1.0 μm的著色圖案中，藉由SEM觀察測定線寬，評價對曝光量的感度。可以說以相同曝光量照射時，線寬的值越大，感度越高。 (Evaluation of Line Width Sensitivity) In a colored pattern with a line width of 1.0 μm after irradiation at an exposure dose of 400 mJ/m ² to 650 mJ/m ² , the line width was measured by SEM observation to evaluate the sensitivity to the exposure dose. It can be said that when the same exposure is used, the larger the value of the line width, the higher the sensitivity.

[表11] PoB後 80 ms 100 ms 120 ms 130 ms 400 mJ/m ² 500 mJ/m ² 600 mJ/m ² 650 mJ/m ² 鹼可溶性樹脂（B-1）的平均線寬（μm） 1.281 1.328 1.367 1.391 鹼可溶性樹脂（B-2）的平均線寬（μm） 1.398 1.422 1.406 1.532 [Table 11] After PoB 80ms 100 ms 120 ms 130 ms 400mJ/ ^m2 500mJ/ ^m2 600mJ/ ^m2 650mJ/ ^m2 Average line width of alkali-soluble resin (B-1) (μm) 1.281 1.328 1.367 1.391 Average line width of alkali-soluble resin (B-2) (μm) 1.398 1.422 1.406 1.532

可知，使用鹼可溶性樹脂（B-1）所獲得的線寬比使用鹼可溶性樹脂（B-2）所獲得的線寬細。根據該結果，可以說與鹼可溶性樹脂（B-1）相比，鹼可溶性樹脂（B-2）可相對於規定線寬的遮罩減少聚合起始劑量，對增加作為其他成分的例如著色劑的含量而言有用，能夠實現彩色濾光片的薄膜化、濃色化。It can be seen that the line width obtained using the alkali-soluble resin (B-1) is thinner than the line width obtained using the alkali-soluble resin (B-2). Based on this result, it can be said that the alkali-soluble resin (B-2) can reduce the polymerization starting dose with respect to the mask of the specified line width compared with the alkali-soluble resin (B-1), and can increase other components such as colorants. It is useful in terms of its content and can achieve thinner and denser color filters.
