Description
본 발명은 광경화 조성물, 이를 포함하는 유기보호층, 및 이를 포함하는 장치에 관한 것이다.The present invention relates to a photocurable composition, an organic protective layer comprising the same, and a device comprising the same.
광학 표시 장치에 사용되는 유기 전계 발광 소자는 수분 또는 기체와 같은 환경의 영향을 받아 특성의 열화 또는 변질의 문제가 발생하기 쉽다. 구체적으로 수분의 영향을 받아 금속 전계와 유기 발광층의 계면이 박리되거나, 금속의 산화로 고저항화 될 수 있고, 유기물 자체가 수분 또는 산소에 의하여 변질되거나, 외부 또는 내부에서 발생하는 아웃가스에 의하여 유기재료, 전극재료의 산화가 발생하여 유기 전계 발광 소자의 발광 특성이 저하될 수 있다. 따라서 유기 전계 발광 소자는 수분 또는 산소로부터 이를 보호하는 봉지용 조성물에 의하여 봉지되어야 한다.Organic electroluminescent devices used in an optical display device are susceptible to deterioration or deterioration of properties under the influence of an environment such as moisture or gas. Specifically, the interface between the metal field and the organic light emitting layer may be peeled off by the influence of moisture, or may be highly resistant to oxidation of the metal, and the organic material itself may be altered by moisture or oxygen, or may be caused by outgass generated from outside or inside. Oxidation of the organic material and the electrode material may occur to deteriorate the light emission characteristics of the organic EL device. Therefore, the organic electroluminescent device should be encapsulated with a composition for encapsulation that protects it from moisture or oxygen.
유기 전계 발광 소자는 무기 보호층과 유기 보호층이 형성된 다층 구조로 봉지화되고 있다. 무기 보호층은 플라즈마에 의한 증착으로 형성되는데, 이때 플라즈마에 의해 유기 보호층이 식각될 수 있다. 이러한 식각은 유기 보호층의 봉지 기능에 손상을 줄 수 있고, 이로 인해 유기발광소자는 발광 특성이 떨어지고, 신뢰성이 떨어질 수 있다.The organic electroluminescent element is encapsulated in a multilayer structure in which an inorganic protective layer and an organic protective layer are formed. The inorganic protective layer is formed by deposition by plasma, in which the organic protective layer may be etched by the plasma. Such etching may damage the encapsulation function of the organic protective layer, and thus, the organic light emitting diode may have poor luminous properties and may have low reliability.

본 발명의 일 실시예에 따른 광경화 조성물은 하기 식 1으로 표시되는 POC 파라미터 값이 약 0.100 이상 약 0.350 이하이고, 방향족 탄화수소기를 갖는 광경화성 모노머 및 광중합 개시제를 포함할 수 있다.The photocurable composition according to an embodiment of the present invention has a POC parameter value of about 0.100 or more and about 0.350 or less, and may include a photocurable monomer and a photopolymerization initiator having an aromatic hydrocarbon group.

<식 1><Equation 1>
상기 식에서, Pcn은 각 모노머의 방향족 고리의 개수, Ocn은 각 모노머의 O원자 및 S원자의 개수, Wrn은 총 모노머 중 각 모노머의 중량%, Mwn는 모노머의 분자량을 나타낸다.In the above formula, Pc n is the number of aromatic rings of each monomer, Oc n is the number of O atoms and S atoms of each monomer, Wr n is the weight percent of each monomer in the total monomers, Mw n represents the molecular weight of the monomer.
상기 POC 파라미터(phenyl oxygen parameter)는 광경화성 모노머 내의 방향족 고리 함량에서 O, S 원자의 함량을 제외한 것을 계산하여 이를 조성물 평균 분자량으로 나눈 값으로, 상기 POC 파라미터 값은 약 0.100 이상 약 0.350 이하일 수 있다. 상기 POC 파라미터 값을 만족하는 광경화성 모노머를 사용함으로써, 유기 전계 발광 소자 또는 유기 전계 발광 소자 상에 형성된 무기 보호층 상에 유기 보호층을 형성할 때에 플라즈마 처리에 의해 유기 보호층이 손상되는 플라즈마 식각률이 현저하게 낮아 내플라즈마성이 높은 유기 보호층을 제공할 수 있다.The POC parameter is a value obtained by subtracting the content of O and S atoms from the aromatic ring content in the photocurable monomer and dividing it by the composition average molecular weight. The POC parameter value may be about 0.100 or more and about 0.350 or less. . By using a photocurable monomer that satisfies the POC parameter value, the plasma etching rate at which the organic protective layer is damaged by plasma treatment when the organic protective layer is formed on the organic electroluminescent device or the inorganic protective layer formed on the organic electroluminescent device. This remarkably low level can provide an organic protective layer with high plasma resistance.
더욱이, POC 파라미터 값이 약 0.100미만인 경우에는 플라즈마 식각율이 높아져 유기막이 손상되어 소자의 신뢰성이 저하될 수 있으며, 약 0.350 이상인 경우에는 점도 상승으로 인하여 공정에 적합하지 않을 수 있다. Furthermore, when the POC parameter value is less than about 0.100, the plasma etch rate may be increased to damage the organic layer, thereby lowering the reliability of the device. When the POC parameter value is greater than about 0.350, the POC parameter may not be suitable for the process due to the viscosity increase.
상기 POC 파라미터 값은 예를 들어 약 0.100 이상 약 0.230이하일 수 있으며, 약 0.100 이상 약 0.190이하 일 수 있으며, 약 0.108 이상 약 0.187 이하 일 수 있다. The POC parameter value may be, for example, about 0.100 or more and about 0.230 or less, about 0.100 or more and about 0.190 or less, and about 0.108 or more and about 0.187 or less.
상기 Pcn은 각 모노머의 방향족 고리의 개수를 나타낸다. 상기 방향족 고리의 개수는 모노머에 포함되는 단일환의 개수를 의미하며, 축합환인 경우 축합된 각 단일환의 개수를 의미한다. 예를 들어, 모노머가 하나의 나프틸기를 포함하는 경우 단일환인 벤젠고리 2개가 축합된 것이므로 Pcn은 2이며, 모노머가 하나의 안트라센기 또는 페난트렌기를 포함하는 경우 Pcn은 3이다.Pc n represents the number of aromatic rings in each monomer. The number of the aromatic rings means the number of monocycles contained in the monomer, and in the case of a condensed ring, it means the number of condensed monocycles. For example, when the monomer contains one naphthyl group, Pc n is 2 since two monocyclic benzene rings are condensed, and Pc n is 3 when the monomer includes one anthracene group or a phenanthrene group.
상기 Ocn은 각 모노머의 "O 원자 및 S원자의 개수"이나, 아크릴레이트에 포함된 "O"의 개수는 포함하지 않는다. 예를 들어, 모노머가 도데칸디올 디메타아크릴레이트인 경우 Ocn은 0이며, 모노머가 페닐티오에틸 아크릴레이트인경우 Ocn은 1 이다.Oc n does not include the number of "O atoms and S atoms" of each monomer and the number of "O" contained in the acrylate. For example, Oc n is 0 when the monomer is dodecanediol dimethacrylate and Oc n is 1 when the monomer is phenylthioethyl acrylate.
상기 Wrn은 총 모노머 중 각 모노머의 중량%로 예를 들어, 조성물에 사용된 모노머가 도데칸디올 디메타아크릴레이트 60 kg 및 페닐티오에틸아크릴레이트 40 kg로 혼재되어 있다면, 도데칸디올 디메타아크릴레이트의 Wrn은 (60/100) X100= 60 이며, 페닐티오에틸아크릴레이트의 Wrn은 (40/100)X100= 40이다. Wr n is the weight percentage of each monomer in the total monomers. For example, if the monomers used in the composition are mixed with 60 kg of dodecanediol dimethacrylate and 40 kg of phenylthioethylacrylate, dodecanediol dimetha Wr n of acrylate is (60/100) X 100 = 60, and Wr n of phenylthioethyl acrylate is (40/100) X 100 = 40.
본 발명에서, 방향족 탄화수소기를 갖는 광경화성 모노머는 Pcn 이 1 이상이며, Pcn 이 1 이상 5 이하 일 수 있고, 일 예에서 Pcn 이 1 이상, Pcn이 2 이상, Pcn이 3 이상 일 수 있으며; Pcn이 2 이상 5 이하일 수 있고, Pcn 이 1 이상 4 이하일 수 있고, Pcn 이 1 이상 3 이하일 수 있다. 상기 범위 내에서, 플라즈마 식각율이 낮아져 유기막이 손상되지 않아 소자의 신뢰성이 향상될 수 있는 동시에 공정상 유리한 효과를 나타낼 수 있다.In the present invention, the photocurable monomer having an aromatic hydrocarbon group Pc n is 1 or more, Pc n may be 1 or more and 5 or less, in one embodiment Pc n is 1 or more, Pc n is 2 or more, Pc n is 3 or more Can be; Pc n may be 2 or more and 5 or less, Pc n may be 1 or more and 4 or less, and Pc n may be 1 or more and 3 or less. Within this range, the plasma etch rate is lowered so that the organic layer is not damaged and thus the reliability of the device can be improved, and at the same time, an advantageous process can be achieved.
상기 방향족 탄화수소기를 갖는 광경화성 모노머 및/또는 방향족 탄화수소기를 갖지 않는 광경화성 모노머는 광중합 개시제에 의해 경화 반응할 수 있는 광경화성 모노머를 의미한다. 상기 광경화성 모노머는 실리콘(Si)을 포함하지 않는 비-실리콘계 모노머를 사용할 수 있으며, 예를 들어 C, H, O, N 또는 S에서 선택되는 원소 만으로 이루어진 모노머일 수 있으나 이에 한정되지 않는다. 광경화성 모노머는 통상의 합성방법으로 합성하여 사용하거나 상업적으로 판매하는 제품을 구입하여 사용할 수 있다. The photocurable monomer which has the said aromatic hydrocarbon group and / or the photocurable monomer which does not have an aromatic hydrocarbon group means the photocurable monomer which can harden-react with a photoinitiator. The photocurable monomer may be a non-silicone monomer that does not include silicon (Si), and may be, for example, a monomer including only an element selected from C, H, O, N, or S, but is not limited thereto. The photocurable monomer may be synthesized by a conventional synthetic method, or may be used by purchasing a commercially available product.
