Abstract: 본발명은전기발광소자에이용될수 있는우레탄기를포함하고있는새로운폴리(1,4-페닐렌비닐렌)(PPV) 유도체의합성과, 이를이용한전기발광소자에관한것이다. PPV는물이나유기용매에용해가능한선 중합체로부터합성되어지며원하는형태의필름으로제조된후 열처리과정을거쳐최종고분자를얻을수 있다. 최근에는고분자의가공성을향상시키기위해최종고분자가유기용해가능한 PPV 유도체들이합성되어지고있으며고분자발광소자의발광물질로서많은연구가진행되고있다. 그러나지금까지개발된 PPV 유도체들은, PPV의곁가지에소수성의긴 알킬그룹을도입한것이대부분이었다. 이러한소수성알킬그룹은용해도를증가시켜 PPV를유기용매에녹게하지만단일층 전기발광소자의경우 ITO나금속전극과의계면접착력이좋지못하고, 다층박막소자의경우전하수송층과의계면접착력이좋지못하다. 낮은접착력때문에정공과전자의주입이효율적이지못하고소자의내구성이떨어지는단점이있다. 본발명에서새로이합성된 PPV 유도체는, 고분자사슬내에수소결합을할 수있는친수성의우레탄기를포함하고있어, ITO나금속전극과의접착력이우수하고전하수송층과의계면접착력도우수하여전기발광소자의효율과소자의내구성을향상시킨다.

Abstract: PURPOSE: An organic electroluminescent device having a double insulating layer is provided to enhance the luminescence and the durability by using the electrical characteristic between a luminous layer and an electrode by inserting a double insulating layer between the luminous layer and the electrode. CONSTITUTION: An organic electroluminescent device comprises an anode(12) for injecting the hole into the substrate(11), an organic luminous layer(15) for emitting light in response to the recombination of injected holes and injected electrons, a cathode(19) for injecting an electron, the first insulating layer(14) placed between the organic luminous layer and the anode, and the second insulating layer(17) for performing the electron blocking. The first insulating layer prevents the electrons from flowing organic luminous layer, which increases the electroluminescent efficiency. The second insulating layer increases the recombination probability.

Abstract: 본발명은백라이트유닛에포함되는도광판의제조방법및 이에의해제조된도광판을제공한다. 이방법은, 투명한평판의일면상에표면거칠기가큰 폴리머박막을형성함으로써, 후속의마이크로렌즈형성용액의젖음성(wettability)이떨어지게되어, 최종적으로형성되는마이크로렌즈의평균폭이작으며, 편평비(aspect ratio)가커지게된다. 이로써도광판의광손실을줄일수 있으며도광판의제조단가를낮출수 있다.
