  • Publication number: 20070085075
    Abstract: To provide an aspect of a novel display device using a light emitting element which is composed of a cathode, an EL layer and an anode, and a manufacturing device of the display device. According to the present invention, dual-sided emission display can be performed in one sheet white color light emitting panel 1001 in which, for example, different images can be displayed on a topside screen and backside screen (full color display, monochrome display or area color display). Two polarizing plates 1002, 1003 are formed by shifting the position thereof with an angular deviation of 90 degrees each other so as to prevent outside light from passing through the pane, thereby realizing a black display when not displayed.

  • Patent number: 7199515
    Abstract: 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.

  • Patent number: 7195801
    Abstract: A manufacturing system capable of enhancing reliability and luminance of a light emitting element is provided which uses an EL material of very high purity in evaporation. The system is also capable of using an EL material efficiently. Instead of a glass jar, a container (first container 11a) to be set in an evaporation apparatus is employed and a material maker (18) stores an EL material (12), or refines it by sublimation and stores, directly in the container. The container is then transferred to a light emitting device maker (19) for evaporation. With a manufacturing system as such, impurities are prevented from contaminating a highly pure EL material. This system also eliminates the trouble of transferring an EL material from a glass jar to a container. The container may be recovered by the material maker and the EL material remaining in the container may be collected for reuse by the manufacturing system.

  • Patent number: 7190335
    Abstract: 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.
