摘要： Although an ink jet method known as a method of selectively forming a film of a high molecular species organic compound, can coat to divide an organic compound for emitting three kinds (R, G, B) of light in one step, film forming accuracy is poor, it is difficult to control the method and therefore, uniformity is not achieved and the constitution is liable to disperse. In contrast thereto, according to the invention, a film comprising a high molecular species material is formed over an entire face of a lower electrode connected to a thin film transistor by a coating method and thereafter, the film comprising the high molecular species material is etched by etching by plasma to thereby enable to selectively form a high molecular species material layer. Further, the organic compound layer is constituted by a material for carrying out luminescence of white color or luminescence of single color and combined with a color changing layer or a coloring layer to thereby realize full color formation.

摘要： An ink jet method known as a method for selectively forming a layer made of a polymeric organic compound is advantageous in that a layer containing an organic compound can be separately colored for emitting light of three colors (R, G, B) at a time. However, this ink jet method is disadvantageous in its poor film formation accuracy, and therefore, it is difficult to control the formation of the film for obtaining the uniformity. As a result, the obtained film is likely to have unevenness. In the present invention, an layer containing an organic compound is formed on the entire surface of a lower electrode connected to a thin film transistor by application. After forming an upper electrode on the lower electrode, an layer containing an organic compound is etched in a self-aligned manner by plasma etching using the upper electrode as a mask so as to allow the selective formation of an layer containing an organic compound. Furthermore, for connection with the upper electrode, the electrical connection is achieved by using an adhesive containing a conductive particle or a paste. Furthermore, a material emitting white light or a material emitting monochromatic light is used as the layer containing an organic compound. The full-color display is achieved by combining the layer containing an organic compound with a color conversion layer or a colored layer.
摘要翻译：作为选择性地形成由聚合有机化合物构成的层的方法的喷墨方法的优点在于，含有有机化合物的层可以分别着色，以一次发射三种颜色（R，G，B）的光。然而，该喷墨法的成膜精度差，因此难以控制膜的形成以获得均匀性。结果，得到的薄膜很可能具有不均匀性。在本发明中，通过施加在与薄膜晶体管连接的下电极的整个表面上形成含有有机化合物的层。在下电极上形成上电极之后，通过使用上电极作为掩模的等离子体蚀刻以自对准的方式蚀刻含有有机化合物的层，以允许选择性地形成含有有机化合物的层。此外，为了与上部电极连接，通过使用含有导电粒子或糊料的粘合剂来实现电连接。此外，使用发射白光的材料或发射单色光的材料作为含有机化合物的层。通过将包含有机化合物的层与颜色转换层或着色层组合来实现全色显示。

摘要： An organic light emitting element which can employ non-sublimable (non-volatile) or insoluble materials while keeping the same level of light emission as prior art is provided. Dispersive particles (202a) of an insoluble organic material that is dispersed in a solvent (201) in which a soluble organic material (203a) is dissolved is applied to a substrate (200) that has an electrode. Then, the solvent (201) is vaporized by heat treatment to form a uniform film (203b) of the soluble organic material in which aggregations (clusters) of the insoluble organic material are scattered. Since the soluble organic material film (203b) is thoroughly uniform, defects such as breakdown can be avoided to make it a fully functional organic light emitting element.

摘要： The present invention is a fabrication method of a light-emitting device characterized by ejecting a solution containing a luminescent material toward an anode or a cathode under a reduced pressure and characterized in that in a duration before the solution is arrived at the anode or the cathode, the solvent in the solution is volatilized, the remaining part of the luminescent material is deposited on the anode or the cathode, and thereby formed a light-emitting layer. By the present invention, a baking process for thickness reduction is not required after applying the solution. Accordingly, it is possible to provide a fabrication method with high throughput although the method is low in cost and simple.
