用以實施發明之形態 本發明係關於一種更詳言之係關於一種可製造彩色濾光片之光敏樹脂組成物，其藉由包含光致發光量子點粒子、光聚合性化合物、於0.001莫耳濃度下365nm波長之UV吸光度為0.1以下之光聚合起始劑、鹼可溶性樹脂及溶劑，以顯著改善亮度及色彩重現性。 以下詳細說明有關本發明。 ＜光敏樹脂組成物＞ 一種光敏樹脂組成物，其包含量子點粒子、光聚合性化合物、光聚合起始劑、鹼可溶性樹脂及溶劑。 光致發光量子點粒子 本發明之光敏樹脂組成物包含光致發光量子點粒子。 量子點為奈米尺寸之半導體物質。原子組成分子，分子構成所謂叢集之小分子集合體，組成奈米粒子，特別於該類各奈米粒子帶有半導體特性時，稱之為量子點。 量子點若從外部被加以能量而成為浮動狀態時，自身會釋出與該能帶隙相應之能量。 本發明之光敏樹脂組成物包含該類光致發光量子點粒子，從其製造之彩色濾光片可藉由光照射而發光(光致發光)。 於包括彩色濾光片之圖像顯示裝置，藉由白色光穿透彩色濾光片來具體呈現彩色，但該過程中，由於光的一部分被彩色濾光片吸收，因此光效率降低。 然而，包括從本發明之光敏樹脂組成物製造之彩色濾光片時，由於彩色濾光片藉由光源的光而自發光，因此可實現更良好的光效率。 又，由於發出具有色相的光，因此色彩重現性更優秀，由於藉由光致發光，往所有方向發出光，因此亦可改善視角。 本發明之量子點粒子若是可藉由光刺激而發光之量子點粒子均可，未特別限定，可從例如II‒VI族半導體化合物、III‒V族半導體化合物、IV‒VI族半導體化合物、IV族元素或包含該元素之化合物、及該等之組合所組成的群組中選擇。該等可單獨使用，或混合兩種以上使用。 前述II‒VI族半導體化合物可從以下化合物所組成的群組中選擇：從CdS、CdSe、CdTe、ZnS、ZnSe、ZnTe、ZnO、HgS、HgSe、HgTe、及該等之混合物所組成的群組中選擇之2元素化合物；從CdSeS、CdSeTe、CdSTe、ZnSeS、ZnSeTe、ZnSTe、HgSeS、HgSeTe、HgSTe、CdZnS、CdZnSe、CdZnTe、CdHgS、CdHgSe、CdHgTe、HgZnS、HgZnSe、HgZnTe及該等之混合物所組成的群組中選擇之3元素化合物；及從CdZnSeS、CdZnSeTe、CdZnSTe、CdHgSeS、CdHgSeTe、CdHgSTe、HgZnSeS、HgZnSeTe、HgZnSTe、及該等之混合物所組成的群組中選擇之4元素化合物；前述III‒V族半導體化合物可從以下化合物所組成的群組中選擇：從GaN、GaP、GaAs、GaSb、AlN、AlP、AlAs、AlSb、InN、InP、InAs、InSb、及該等之混合物所組成的群組中選擇之2元素化合物；從GaNP、GaNAs、GaNSb、GaPAs、GaPSb、AlNP、AlNAs、AlNSb、AlPAs、AlPSb、InNP、InNAs、InNSb、InPAs、InPSb、GaAlNP、及該等之混合物所組成的群組中選擇之3元素化合物；及從GaAlNAs、GaAlNSb、GaAlPAs、GaAlPSb、GaInNP、GaInNAs、GaInNSb、GaInPAs、GaInPSb、InAlNP、InAlNAs、InAlNSb、InAlPAs、InAlPSb、及該等之混合物所組成的群組中選擇之4元素化合物；前述IV‒VI族半導體化合物可從以下化合物所組成的群組中選擇：從SnS、SnSe、SnTe、PbS、PbSe、PbTe、及該等之混合物所組成的群組中選擇之2元素化合物；從SnSeS、SnSeTe、SnSTe、PbSeS、PbSeTe、PbSTe、SnPbS、SnPbSe、SnPbTe、及該等之混合物所組成的群組中選擇之3元素化合物；及從SnPbSSe、SnPbSeTe、SnPbSTe、及該等之混合物所組成的群組中選擇之4元素化合物；前述IV族元素或包含該元素之化合物可從以下化合物所組成的群組中選擇：從Si、Ge、及該等之混合物所組成的群組中選擇之元素化合物；及SiC、SiGe、及該等之混合物所組成的群組中選擇之2元素化合物。 量子點粒子可為均質(homogeneous)之單一構造，核體‒殼體(core‒shell)、漸變(gradient)構造等類之雙重構造，或該等之混合構造。 就核體‒殼體(core‒shell)雙重構造而言，分別構成核體(core)與殼體(shell)之物質可由前述提到、各自不同的半導體化合物組成。例如前述殼體可包含從CdSe、CdS、ZnS、ZnSe、CdTe、CdSeTe、CdZnS、PbSe、AgInZnS及ZnO所組成的群組中選擇之一種以上的物質，但不限定於此。前述殼體可包含從CdSe、ZnSe、ZnS、ZnTe、CdTe、PbS、TiO、SrSe及HgSe所組成的群組中選擇之一種以上的物質，但不限定於此。 本發明之量子點粒子之直徑並未特別限定，例如平均粒徑可為1～40nm。然後，於核體‒殼體(core‒shell)雙重構造的情況下，核體之平均粒徑可為0.5～10nm，殼體之平均厚度可為0.5～30nm。平均粒徑及厚度為前述範圍內時，組成物內可具有優秀的分散性，可藉由光照射具體呈現色彩，用於製造彩色濾光片。 如同一般的彩色濾光片製造所用之著色光敏樹脂組成物，為了具體呈現色相而包含紅、綠、藍著色劑，光致發光量子點粒子亦可分類為紅量子點粒子、綠量子點粒子及藍量子點粒子，本發明之量子點粒子可為紅量子點粒子、綠量子點粒子或藍量子點粒子。 前述紅、綠及藍量子點粒子可依粒徑來分類，粒徑依紅、綠、藍色順序變小。具體而言，紅量子點粒子之粒徑為5nm以上～10nm以下，綠量子點粒子可超過3nm～5nm以下，藍量子點粒子可為1nm以上～3nm以下。 於光照射時，紅量子點粒子發出紅色光，綠量子點粒子發出綠色光，藍量子點粒子發出藍色光。 量子點粒子可藉由濕式化學製程(wet chemical process)、有機金屬化學蒸鍍製程或分子束磊晶製程來合成。濕式化學製程係於有機溶劑放入前驅物物質以使粒子生長的方法。由於結晶生長時，有機溶劑會自然配位於量子點結晶的表面，發揮分散劑的功能，從而調節結晶生長，因此比起諸如有基金屬化學蒸鍍(MOCVD，metal organic chemical vapor deposition)或分子束磊晶(MBE，molecular beam epitaxy)之氣相蒸鍍法，可容易透過低廉的製程來控制奈米粒子生長。 本發明之量子點粒子之含量並未特別限定，例如光敏樹脂組成物之固形物總重量中，可含3～80重量%，更宜含5～70重量%。若含量小於3重量%，發光效率容易變得微不足道，若超過80重量%，其他組成的含量相對不足，具有難以形成像素圖型的問題點。 光聚合性化合物 本發明之光聚合性化合物係可藉由後述之光聚合起始劑的作用來聚合之化合物，可舉出單官能單體、二官能單體、其他多官能單體等。該等光聚合性化合物可單獨使用，或混合兩種以上使用。 單官能性單體之具體例可舉出壬基苯基丙烯酸卡必酯、2-羥基-3-苯氧丙烯酸丙酯、2-乙基己基丙烯酸卡必酯、2-羥基丙烯酸乙酯、N-乙烯基砒喀烷酮等。 二官能性單體之具體例可舉出1,6–己二醯二(甲基)丙烯酸酯、乙二醇二(甲基)丙烯酸酯、新戊二醇二(甲基)丙烯酸酯、三乙二醇二(甲基)丙烯酸酯、雙酚A之雙(丙烯醯氧乙基)醚、3-甲基戊烷二醇(甲基)丙烯酸酯等。 其他多官能單體之具體例可舉出三羥甲基丙烷三(甲基)丙烯酸酯、乙氧基化(乙氧化)三羥甲基丙烷三(甲基)丙烯酸酯、丙氧基化(丙氧化)三羥甲基丙烷三(甲基)丙烯酸酯、季戊四醇三(甲基)丙烯酸酯、季戊四醇四(甲基)丙烯酸酯、二季戊四醇五(甲基)丙烯酸酯、乙氧基化二季戊四醇六(甲基)丙烯酸酯、丙氧基化二季戊四醇六(甲基)丙烯酸酯、二季戊四醇六(甲基)丙烯酸酯、如下述化學式1具有羥價之二季戊四醇(聚)丙烯酸酯等。 [化學式1](式中之R為氫原子或碳數2～6之丙烯醯基)。 本發明之光聚合性化合物之含量並未特別限定，例如光敏樹脂組成物之固形物總重量中，可含5～70重量%，更宜含10～60重量%。若含量小於5重量%，光硬化度降低，可能難以形成像素圖型，若超過70重量%，圖型可能剝離。 光聚合起始劑 本發明之光聚合起始劑係於0.001莫耳濃度下365nm波長之UV吸光度為0～0.1以下。若於0.001莫耳濃度下，365nm波長之UV吸光度超過0.1，則難以形成微圖型，以本發明之組成物形成之彩色濾光片之光致發光的強度降低，無法實現具有充分亮度之顯示裝置。 然而，由於本發明包含0.001莫耳濃度下365nm波長之UV吸光度為0.1以下之光聚合起始劑，因此可容易形成微圖型，可使光致發光量子點粒子之光致發光強度極大化，顯著改善亮度。判斷此係由於若UV吸光度超過0.1，光聚合起始劑會與光致發光量子點粒子競相吸收UV，光致發光量子點粒子之UV吸光量減少，發光效率降低，若為0.1以下，光致發光量子點粒子吸收遠比光聚合起始劑多量的UV光，發光效率受到改善。 具體而言，由於就光致發光量子點粒子之發光效率面而言，光聚合起始劑0.001莫耳濃度下，365nm波長之UV吸光度越接近0越佳，就微圖型形成面而言，吸光度越接近0.1越佳，因此本發明之光聚合起始劑係於0.001莫耳濃度下，365nm波長之UV吸光度得為0以上～0.1以下。 本發明之光聚合起始劑若具有前述範圍之吸光度均可，並未特別限定，可舉出例如具有前述範圍之吸光度之苯乙酮系化合物、多官能硫醇系化合物、聯咪唑系化合物、肟酯系化合物、三嗪系化合物等。該等化合物可單獨使用，或混合兩種以上使用。

本發明之彩色濾光片適用於圖像顯示裝置時，由於藉由顯示裝置光源的光發光，因此可實現更佳的光效率。又，由於發出具有色相的光，因此色彩重現性更優秀，由於藉由光致發光，往所有方向發出光，因此亦可改善視角。 彩色濾光片包含基板及形成於前述基板上部之圖型層。 基板為彩色濾光片本身，或彩色濾光片位於顯示器裝置等之部位均可，並未特別限制。前述基板亦可為矽(Si)、矽氧化物(SiOx

添加下述表1所記載的組成(重量部)，以丙二醇單甲醚乙酸酯稀釋，使得固形物成為18重量%後，予以攪拌，製造光敏樹脂組成物。 [表1] (2) 彩色濾光片之製造
以旋轉塗布法，於玻璃基板上塗布實施例及比較例之光敏樹脂組成物後，載置於加熱板上，以100℃的溫度維持3分鐘，形成薄膜。於前述薄膜上，載置具有20mm´20mm正方形之穿透圖型及1～100mm之線/間距圖型之試驗光罩，設定與試驗光罩的間隔為100mm，照射紫外線。 此時，紫外線之光源為USHIO電機之超高壓水銀燈(USH‒250D)，於大氣氣氛下，以200mJ/cm2
之曝光量(365nm)照射光，不使用光學濾光片。接著，將前述薄膜浸泡於pH10.5之KOH水溶液80秒鐘而顯影。 以蒸餾水洗淨後，吹送氮氣予以乾燥，以150℃之烤箱加熱10分鐘，製造彩色濾光片。製造之彩色圖型之厚度為3.0μm。實驗例 (1) 光聚合起始劑之吸光度測定

A photopolymerization initiator, an alkali-soluble resin, and a solvent having a UV absorbance of 365 nm at a concentration of 0.1 or less at a concentration to remarkably improve brightness and color reproducibility. The invention is described in detail below. <Photosensitive Resin Composition> A photosensitive resin composition comprising quantum dot particles, a photopolymerizable compound, a photopolymerization initiator, an alkali-soluble resin, and a solvent. Photoluminescence Quantum Dot Particles The photosensitive resin composition of the present invention comprises photoluminescent quantum dot particles. Quantum dots are semiconductor materials of nanometer size. Atom consists of molecules, which form a collection of small molecules called clusters, which form nanoparticles. Especially when these nanoparticles have semiconductor properties, they are called quantum dots. When a quantum dot is energized from the outside and becomes a floating state, it releases its energy corresponding to the band gap. The photosensitive resin composition of the present invention contains such photoluminescent quantum dot particles, and a color filter produced therefrom can be illuminated by photoirradiation (photoluminescence). In an image display device including a color filter, color is specifically exhibited by white light penetrating a color filter, but in this process, since a part of light is absorbed by the color filter, light efficiency is lowered. However, when the color filter manufactured from the photosensitive resin composition of the present invention is included, since the color filter self-illuminates by the light of the light source, more excellent light efficiency can be achieved. Further, since light having a hue is emitted, color reproducibility is more excellent, and since light is emitted in all directions by photoluminescence, the viewing angle can also be improved. The quantum dot particles of the present invention are not particularly limited as long as they can emit light by light stimulation, and can be, for example, a Group II‒VI semiconductor compound, a III‒V semiconductor compound, an IV‒VI semiconductor compound, or IV. A group consisting of a group element or a compound comprising the element, and a combination of the combinations. These may be used singly or in combination of two or more. The Group II ‒ VI semiconductor compound may be selected from the group consisting of CdS, CdSe, CdTe, ZnS, ZnSe, ZnTe, ZnO, HgS, HgSe, HgTe, and a mixture thereof. a 2-element compound selected from the group consisting of CdSeS, CdSeTe, CdSTe, ZnSeS, ZnSeTe, ZnSTe, HgSeS, HgSeTe, HgSTe, CdZnS, CdZnSe, CdZnTe, CdHgS, CdHgSe, CdHgTe, HgZnS, HgZnSe, HgZnTe, and the like a 3-element compound selected from the group; and a 4-element compound selected from the group consisting of CdZnSeS, CdZnSeTe, CdZnSTe, CdHgSeS, CdHgSeTe, CdHgSTe, HgZnSeS, HgZnSeTe, HgZnSTe, and mixtures thereof; The group V semiconductor compound can be selected from the group consisting of GaN, GaP, GaAs, GaSb, AlN, AlP, AlAs, AlSb, InN, InP, InAs, InSb, and a mixture thereof. a 2-element compound selected from the group; from a combination of GaNP, GaNAs, GaNSb, GaPAs, GaPSb, AlNP, AlNAs, AlNSb, AlPAs, AlPSb, InNP, InNAs, InNSb, InPAs, InPSb, GaAlNP, and the like a 3-element compound selected from the group consisting of: and a mixture of GaAlNAs, GaAlNSb, GaAlPAs, GaAlPSb, GaInNP, GaInNAs, GaInNSb, GaInPAs, GaInPSb, InAlNP, InAlNAs, InAlNSb, InAlPAs, InAlPSb, and the like a 4-element compound selected from the group; the aforementioned IV‒VI semiconductor compound may be selected from the group consisting of SnS, SnSe, SnTe, PbS, PbSe, PbTe, and mixtures thereof. a 2-element compound selected from the group; a 3-element compound selected from the group consisting of SnSeS, SnSeTe, SnSTe, PbSeS, PbSeTe, PbSTe, SnPbS, SnPbSe, SnPbTe, and mixtures thereof; and from SnPbSSe, SnPbSeTe, a 4-element compound selected from the group consisting of SnPbSTe, and mixtures thereof; the Group IV element or a compound comprising the element may be selected from the group consisting of Si, Ge, and the like. An elemental compound selected from the group consisting of a mixture; and a 2-element compound selected from the group consisting of SiC, SiGe, and mixtures thereof. The quantum dot particles may be a homogeneous single structure, a core ‒ shell, a gradient structure, or the like, or a hybrid structure thereof. In the case of a double structure of a core ‒ shell, substances constituting a core and a shell, respectively, may be composed of the semiconductor compounds mentioned above and different from each other. For example, the casing may include one or more selected from the group consisting of CdSe, CdS, ZnS, ZnSe, CdTe, CdSeTe, CdZnS, PbSe, AgInZnS, and ZnO, but is not limited thereto. The casing may include one or more selected from the group consisting of CdSe, ZnSe, ZnS, ZnTe, CdTe, PbS, TiO, SrSe, and HgSe, but is not limited thereto. The diameter of the quantum dot particles of the present invention is not particularly limited, and for example, the average particle diameter may be from 1 to 40 nm. Then, in the case of a double structure of a core ‒ shell, the average particle diameter of the core body may be 0.5 to 10 nm, and the average thickness of the shell may be 0.5 to 30 nm. When the average particle diameter and the thickness are within the above range, the composition can have excellent dispersibility, and can be specifically colored by light irradiation to produce a color filter. Like the colored photosensitive resin composition used in the manufacture of a general color filter, in order to specifically exhibit a hue, a red, green, and blue coloring agent is included, and the photoluminescent quantum dot particles may be classified into red quantum dot particles, green quantum dot particles, and The blue quantum dot particles, the quantum dot particles of the present invention may be red quantum dot particles, green quantum dot particles or blue quantum dot particles. The red, green and blue quantum dot particles can be classified according to the particle diameter, and the particle diameter becomes smaller in the order of red, green and blue. Specifically, the particle diameter of the red quantum dot particles is 5 nm or more and 10 nm or less, the green quantum dot particles may exceed 3 nm to 5 nm, and the blue quantum dot particles may be 1 nm or more and 3 nm or less. When illuminated by light, red quantum dot particles emit red light, green quantum dot particles emit green light, and blue quantum dot particles emit blue light. Quantum dot particles can be synthesized by a wet chemical process, an organometallic chemical vapor deposition process, or a molecular beam epitaxy process. The wet chemical process is a method in which an organic solvent is placed in a precursor material to grow particles. Since crystal growth occurs, the organic solvent naturally occupies the surface of the quantum dot crystal to function as a dispersant, thereby regulating crystal growth, and thus is compared with, for example, metal organic chemical vapor deposition (MOCVD) or molecular beam. The vapor phase evaporation method of MBE (molecular beam epitaxy) can easily control the growth of nano particles through an inexpensive process. The content of the quantum dot particles of the present invention is not particularly limited. For example, the total weight of the solid content of the photosensitive resin composition may be from 3 to 80% by weight, more preferably from 5 to 70% by weight. When the content is less than 3% by weight, the luminous efficiency tends to be negligible, and if it exceeds 80% by weight, the content of other components is relatively insufficient, which has a problem that it is difficult to form a pixel pattern. Photopolymerizable Compound The photopolymerizable compound of the present invention is a compound which can be polymerized by the action of a photopolymerization initiator described later, and examples thereof include a monofunctional monomer, a difunctional monomer, and other polyfunctional monomers. These photopolymerizable compounds may be used singly or in combination of two or more. Specific examples of the monofunctional monomer include mercaptophenyl carbitol, 2-hydroxy-3-phenoxy propyl acrylate, 2-ethylhexyl acrylic acid carbamide, 2-hydroxyethyl acrylate, and N. - Vinyl quinone and the like.

[Chemical Formula 1] (wherein R is a hydrogen atom or an acryloyl group having 2 to 6 carbon atoms). The content of the photopolymerizable compound of the present invention is not particularly limited. For example, the total weight of the solid content of the photosensitive resin composition may be 5 to 70% by weight, more preferably 10 to 60% by weight. If the content is less than 5% by weight, the degree of photohardening is lowered, and it may be difficult to form a pixel pattern, and if it exceeds 70% by weight, the pattern may be peeled off. Photopolymerization initiator The photopolymerization initiator of the present invention has a UV absorbance of 0 to 0.1 or less at a wavelength of 365 nm at a concentration of 0.001 mol. If the UV absorbance at a wavelength of 365 nm exceeds 0.1 at a concentration of 0.001 m, it is difficult to form a micropattern, and the intensity of photoluminescence of the color filter formed by the composition of the present invention is lowered, and display with sufficient brightness cannot be realized. Device. However, since the present invention contains a photopolymerization initiator having a UV absorbance of 365 nm at a wavelength of 0.001 m or less, it is easy to form a micropattern, and the photoluminescence intensity of the photoluminescence quantum dot particles can be maximized. Significantly improved brightness. It is judged that if the UV absorbance exceeds 0.1, the photopolymerization initiator will compete with the photoluminescence quantum dot particles to absorb UV, and the UV absorption amount of the photoluminescence quantum dot particles is reduced, and the luminous efficiency is lowered, and if it is 0.1 or less, the light is caused. The luminescent quantum dot particles absorb much more UV light than the photopolymerization initiator, and the luminous efficiency is improved. Specifically, in terms of the light-emitting efficiency surface of the photoluminescent quantum dot particles, the photo-polymerization initiator has a UV absorbance at a wavelength of 365 nm which is closer to 0, and the micro-pattern forming surface is The closer the absorbance is to 0.1, the photopolymerization initiator of the present invention is at a concentration of 0.001 mol, and the UV absorbance at a wavelength of 365 nm is 0 or more and 0.1 or less.

(2) Whether the micropattern formation can be evaluated on the color filter manufactured from the compositions of the foregoing examples and comparative examples, and the OM equipment (ECLIPSELV 100POL, NIKON) is used to measure the line/space mask having a width of 100 μm through the opening. The width of the pattern is determined by the difference between the width of the opening of the mask and the width of the pattern, which is shown in Table 2 below. The smaller the difference between the width of the opening of the mask and the width of the pattern, the more detailed the pattern can be formed. If the absolute value of the difference is 20 μm or more, it is difficult to specifically present the micro pixels, and when the negative value is displayed, the process may be caused. (3) Luminous intensity was measured in a color filter manufactured from the compositions of the foregoing Examples and Comparative Examples, and irradiated with a 365 nm Tube type 4WUV illuminator (VL‒4LC, VILBERLOURMAT) in a pattern portion of 20 mm ́20 mm. The optical intensity of the wavelength emitted by photoluminescence (red quantum dots: 640 nm, green quantum dots: 545 nm) was measured by a spectrometer (Ocean Optics), and is shown in Table 2 below. The stronger the measured light intensity, the more excellent the photoluminescence characteristics can be judged. [Table 2] Referring to the above Table 2, the compositions of Examples 1 to 8 which comprise a photopolymerization initiator having a UV absorbance of 365 nm and a wavelength of 0.1 or less, having a difference in the width of the opening of the mask and the width of the pattern are small. , can form a very fine pattern. Then, it was confirmed that the intensity of photoluminescence was excellent and the brightness was high. However, the compositions of Comparative Examples 1 to 5 were not able to form a micropattern or the photoluminescence intensity was lowered.
