유기 화합물 및 이를 포함하는 유기발광소자 {Organic compound and electroluminescent device comprising the same}Organic compound and organic light emitting device comprising the same {Organic compound and electroluminescent device comprising the same}

본 발명은 유기발광소자에 구비되는 광효율 개선층 (Capping layer) 재료로 채용되는 것을 특징으로 하는 유기 화합물과 이를 채용하여 소자의 저전압 구동과 우수한 발광 효율 등의 발광 특성이 현저히 향상된 유기발광소자에 관한 것이다.The present invention relates to an organic light-emitting device characterized in that it is employed as a material for a capping layer provided in an organic light-emitting device, and an organic light-emitting device having significantly improved light-emitting characteristics such as low-voltage driving and excellent light-emitting efficiency by employing the organic compound. will be.

유기발광소자는 투명 기판 위에도 소자를 형성할 수 있을 뿐 아니라, 플라즈마 디스플레이 패널 (Plasma Display Panel)이나 무기전계발광 (EL) 디스플레이에 비해 10 V 이하의 저전압 구동이 가능하고, 전력 소모가 비교적 적으며, 색감이 뛰어나다는 장점이 있고, 녹색, 청색, 적색의 3가지 색을 나타낼 수가 있어 최근에 차세대 디스플레이 소자로 많은 관심의 대상이 되고 있다.Organic light emitting devices can not only be formed on a transparent substrate, but also can be driven at a low voltage of 10 V or less compared to plasma display panels or inorganic electroluminescent (EL) displays, and consume relatively little power. , It has the advantage of being excellent in color, and can show three colors of green, blue, and red, so it has recently become a subject of much interest as a next-generation display device.

다만, 이러한 유기발광소자가 상기와 같은 특징으로 발휘하기 위해서는 소자 내 유기층을 이루는 물질인 정공주입 물질, 정공수송 물질, 발광물질, 전자수송 물질, 전자주입 물질 등이 안정하고 효율적인 재료에 의하여 뒷받침되는 것이 선행되어야 하나, 아직까지는 안정하고 효율적인 유기발광소자용 유기층 재료의 개발이 충분히 이루어지지 않은 상태이다.However, in order for the organic light emitting device to exhibit the above characteristics, the materials constituting the organic layer in the device, such as hole injection materials, hole transport materials, light emitting materials, electron transport materials, and electron injection materials, are supported by stable and efficient materials. However, the development of stable and efficient organic layer materials for organic light emitting devices has not yet been sufficiently accomplished.

It is desperately needed.

It is considered as one of the important factors to improve performance, and as an example of this method, a capping layer is used on an electrode to increase light efficiency and achieve excellent color purity.

따라서, 본 발명은 유기발광소자에 구비되는 광효율 개선층 (capping layer)에 채용되어 소자의 저전압 구동과 향상된 발광 효율 등의 우수한 발광 특성을 구현할 수 있는 신규한 유기 화합물 및 이를 포함하는 유기발광소자를 제공하고자 한다.Therefore, the present invention provides a novel organic compound capable of realizing excellent light emitting characteristics such as low-voltage driving and improved luminous efficiency by being employed in a light efficiency improvement layer (capping layer) provided in an organic light emitting device and an organic light emitting device including the same. want to provide
