Abstract: PURPOSE: A thick film type ELD and a fabricating method thereof are to restrict generating of an air bubble in a fluorescent layer of the ELD, thereby improving brightness and durability of the device. CONSTITUTION: The first and second electrode is received a voltage from an outside. A fluorescent layer, in which an organic binder containing thermoplastic resin is mixed with a phosphor, is formed between the first and second electrodes. An insulating layer is formed between the fluorescent layer and the second electrode. A mixing rate of the organic binder and the phosphor is 6:4-7:3. The organic binder uses dibasic ester, N and N-dimethylformanide as a solvent for the thermoplastic resin. In the method, the first electrode is formed on a substrate. The organic binder mixed with the phosphor is coated and dried on the first electrode to form the fluorescent layer. An air bubble generated on the fluorescent layer is removed. The insulating layer is formed on the fluorescent layer. The second electrode is then formed on the insulating layer.

Abstract: 이발명은투명한절연층을이용한후막형전계발광소자에관한것이다. 기판위에제1 전극이형성되어있고, 제1 전극위에형광층이형성되어있으며, 형광층위에빛을투과시키는절연층이형성되어있고, 절연층위에제2 전극이형성되어있다. 절연층은형광층의상면과측면을모두감싸는형태로형성되어있다. 제1 전극및 제2 전극에전압이인가되면형광층이빛을발광하고, 형광층으로부터발광된빛은제1 전극을통하여외부로방출되며, 이때 형광층으로부터절연층쪽으로발광된빛도절연층을투과한다음제2 전극에반사되어다시절연층, 형광층및 제1 전극을순차적으로통과하여외부로방출된다. 따라서, 전계발광소자로부터방출되는빛의휘도량이증가되어휘도특성이향상되며, 절연층이형광층을보호함에따라내구성이향상된다.

Abstract: 이발명은후막형전계발광소자및 그제조방법에관한것이다. 기판위에제1 전극이형성되어있으며, 제1 전극위의일부에형광층이형성되어있고, 형광층의일측에인접하여제1 전극위에제1 절연층이형성되어있다. 형광층위에제2 절연층이형성되어있으며, 제1 절연층및 제2 절연층위에제2 전극이형성되어있다. 제1 전극위에형광층의타측에인접하여제1 도전성접착막이형성되어있고, 제1 도전성접착막에제1 전극과전기적으로연결되는제1 단자가접착되어있으며, 제1 절연층위에형성되어있는제2 전극위에제2 도전성접착막이형성되어있으며, 제2 도전성접착막에제2 전극과전기적으로연결되는제2 단자가접착되어있다. 따라서, 외부로부터의전압이제1 및제2 단자를통하여제1 전극및 제2 전극에각각공급됨에따라, 형광층에서빛이발생된다. 또한, 제1 및제2 도전성접착막이비휘발성바인더가첨가된도전성페이스트로이루어짐에따라, 접착성이현저하게향상될뿐만아니라내열성이강한특성을지니고있어외부회로와납땜으로연결되는경우단자부불량발생이현격하게감소되어제1 및제2 단자가해당전극으로부터분리되는것이방지된다.

Abstract: PURPOSE: A thick film type EL(electroluminescence) element using a transparent insulating layer is provided to improve brightness character and durability of the thick film type EL element. CONSTITUTION: A transparent electrode(2) on which a conductor such as an indium tin oxide is applied is formed on a substrate(1). A fluorescence layer(3) on which a fluorescent material as a compound of a ZnS and a CuS is applied is formed on the transparent electrode(2). An insulating layer(4) composed of an insulator permeable by light is formed on the fluorescence layer(3). A rear electrode(5) on which a material having superior reflection character like an aluminum is vacuum evaporated is formed on the insulating layer(4). Because the insulating layer(4) is composed of a parylene having insulating character and light permeability and formed so as to surround the top and the side of the fluorescence layer(3), the insulating layer(4) has insulation and protection function to the fluorescence layer(3). A protective film(6) is formed on top of the substrate(1), the transparent electrode(2), fluorescence layer(3), the insulating layer(4) and the rear electrode(5) to protect whole EL element for moisture-proof.
