  • Publication number: 20160218160
    Abstract: To provide a light emitting device high in reliability with a pixel portion having high definition with a large screen. According to a light emitting device of the present invention, on an insulator (24) provided between pixel electrodes, an auxiliary electrode (21) made of a metal film is formed, whereby a conductive layer (20) made of a transparent conductive film in contact with the auxiliary electrode can be made low in resistance and thin. Also, the auxiliary electrode (21) is used to achieve connection with an electrode on a lower layer, whereby the electrode can be led out with the transparent conductive film formed on an EL layer. Further, a protective film (32) made of a film containing hydrogen and a silicon nitride film which are laminated is formed, whereby high reliability can be achieved.

  • Publication number: 20160190170
    Abstract: The object of the invention is to provide a method for fabricating a semiconductor device having a peeled layer bonded to a base material with curvature. Particularly, the object is to provide a method for fabricating a display with curvature, more specifically, a light emitting device having an OLED bonded to a base material with curvature. An external force is applied to a support originally having curvature and elasticity, and the support is bonded to a peeled layer formed over a substrate. Then, when the substrate is peeled, the support returns into the original shape by the restoring force, and the peeled layer as well is curved along the shape of the support. Finally, a transfer object originally having curvature is bonded to the peeled layer, and then a device with a desired curvature is completed.

  • Publication number: 20160133683
    Abstract: (OBJECT) The object is to provide a lightened semiconductor device and a manufacturing method thereof by pasting a layer to be peeled to various base materials. (MEANS FOR SOLVING THE PROBLEM) In the present invention, a layer to be peeled is formed on a substrate, then a seal substrate provided with an etching stopper film is pasted with a binding material on the layer to be peeled, followed by removing only the seal substrate by etching or polishing. The remaining etching stopper film is functioned as a blocking film. In addition, a magnet sheet may be pasted as a pasting member.

  • Publication number: 20160118445
    Abstract: A light emitting device having a high definition, a high aperture ratio and a high reliability is provided. The present invention realizes a high definition and a high aperture ratio for a flat panel display of full colors using luminescent colors of red, green and blue without being dependent upon the film formation method and deposition precision of an organic compound layer by forming the laminated sections 21, 22 by means of intentionally and partially overlapping different organic compound layers of adjacent light emitting elements. Moreover, the protective film 32a containing hydrogen is formed and the drawback in the organic compound layer is terminated with hydrogen, thereby realizing the enhancement of the brightness and the reliability.

  • Patent number: 9232087
    Abstract: Disclosed is an image processing apparatus composed in a hierarchical architecture of a hardware resource, a first control program over the hardware resource, a second control program and an application program over the first control program. The first control program includes a first API for receiving a first request relating to image processing from the second control program and a second request relating to image processing from the application program, and controls, on receiving either of the first and second requests, the hardware resource to perform image processing based on the received request. The second control program includes a second API publicly released in advance for receiving a third request relating to image processing from an external source, converts the received third request to a command supported by the first API, and passes the command as the first request to the first control program.

  • Publication number: 20150243922
    Abstract: 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.
