| 20090163108 | SELF-EMISSION PANEL AND METHOD OF MANUFACTURING THE SAME - A self-emission panel and a method of manufacturing a self-emission panel which can prevent emission failures from occurring due to various factors, thereby achieving a self-emission panel that is free from emission failures. The self-emission panel is manufactured by forming a first conductive layer on a substrate directly or via other layers, forming a deposition layer including a luminescent layer on the first conductive layer, and forming a second conductive layer on the deposition layer. This manufacturing method includes: a first step of forming a sectioning layer for sectioning an opening for making a emission area on the first conductive layer after the formation of the first conductive layer; a second step of applying surface treatment to at least the surface of the first conductive layer inside the opening; and a third step of depositing a deposition layer on the first conductive layer given surface treatment in the second step. | 06-25-2009 |
| 20090156083 | METHOD OF MANUFACTURING DISPLAY APPARATUS WITH SAW TOUCH SENSOR - First electrodes partially configuring light-emitting elements are patterned in the form of stripes on a first major surface of a transparent substrate. After the step of forming the first electrodes, piezoelectric elements functioning a SAW touch sensor is formed on a second major surface of the transparent substrate. Furthermore, after the step of forming the piezoelectric elements, the light-emitting elements forming step of forming light-emitting elements on the first electrodes which are patterned in advance is sequentially executed. | 06-18-2009 |

| 20090058277 | Organic Electroluminescent Display Device and Chemical Compounds for Liquid Crystals - The new organic electroluminescent display device has a carrier-transporting layer and/or an organic luminous layer composed of a nematic liquid crystal or a liquid crystal dispersing a carrier-transporting low-molecule therein. When the organic luminous layer is to be bestowed with faculty as a liquid crystal, it is made of a nematic liquid crystal. Both the carrier-transporting layer and the organic luminous layer may be bestowed with faculty as a liquid crystal. Since the liquid crystal is incorporated in the carrier-transporting layer and/or the organic luminous layer, the display device can be driven as a liquid crystal display device in a dark place by charging with a voltage lower than a light emission initiating potential. Of course, it is driven as an electroluminescent display device when it is charged with a voltage higher than the light emission initiating potential. Use of an electroluminescent liquid crystal as a organic luminous layer enables omission of a carrier-transporting layer. | 03-05-2009 |
| 20090053963 | ORGANIC EL PANEL AND METHOD OF MANUFACTURING THE SAME - The present invention is to ensure that when it has been judged that film-formation areas of a plurality of layers laminated on the same luminescent areas of organic EL devices involve a defect, it is possible to exactly find which layer of the multi-laminated layers is a defective layer. The film formation areas of layers to be laminated on luminescent area are formed in a manner such that overlap deviations e | 02-26-2009 |
