| 20110018433 | METHOD OF PRODUCING ORGANIC ELECTROLUMINESCENCE ELEMENT, ORGANIC ELECTROLUMINESCENCE ELEMENT, AND DISPLAY DEVICE - A method of producing an organic electroluminescent element according to the present invention is a method of producing an organic electroluminescent element by stacking on a substrate at least a cathode, an anode, and an organic light-emitting layer disposed between the cathode and the anode. The method of the present invention is characterized by comprising: an organic light-emitting layer forming step of forming the organic light-emitting layer by applying an ink comprising an organic light-emitting material to an inside of a partition wall built to surround a pixel region for forming a pixel; and a surface treating step of treating a surface before the organic light-emitting layer forming step with an organic solvent from the side where the partition wall is built with respect to the substrate. According to the method of the present invention, the organic light-emitting layer can be formed without film defects, and a high-quality organic electroluminescent element and a high-quality display device having the organic electroluminescent element are provided. | 01-27-2011 |
| 20100196679 | BARRIER LAYER-ATTACHED SUBSTRATE, DISPLAY COMPONENT, AND METHOD FOR MANUFACTURING DISPLAY COMPONENT - A barrier layer-attached substrate according to the present invention is the barrier layer-attached substrate for a display component comprising: a barrier layer-attached substrate in which the barrier layers are formed on the substrate; a plurality of display elements formed on the barrier layer of the barrier layer-attached substrate; and an upper multilayer sealing film formed on the display elements so as to cover the display elements. And the barrier layer-attached substrate is characterized in that a plurality of the barrier layers are formed on the substrate into a divided pattern. With the use of the barrier layer-attached substrate of the present invention, a long-life display component of the present invention can be manufactured. | 08-05-2010 |
