摘要： An organic electro-luminescence display device emits light by applying a voltage by an image signal between an upper electrode (23) and a lower electrode which sandwich an organic electro-luminescence layer. The organic electro-luminescence layer comprises an electron transporting layer, a light emitting layer, and a hole transporting layer. The electron transporting layer includes an organic material and cesium, and has a moisture absorbing characteristic. A structure in which the same materials as the electron transporting layer are used and which has a different constituent composition and a greater amount of cesium is used as a desiccant (40) and placed in a region which does not overlap the organic electro-luminescence layer, to effectively remove moisture inside the organic electro-luminescence display device.

摘要： The present invention provides a display device which can obviates the possibility of occurrence of sticking as a whole of a display area even when the brightness is relatively changed on a display area. In a display device, a plurality of pixels are arranged in the inside of a display area and the respective pixels include first electrodes to which signals are independently inputted and a common second electrode to which a signal which becomes the reference with respect to the signals is inputted.

摘要： In a top emission type organic EL display device, brightness gradient in a screen is reduced while keeping a screen brightness. A reflection film is formed under a lower electrode and the light from an organic EL layer is emitted through an upper electrode. Light absorption of the upper electrode is larger on the side of a shorter wavelength. When a film thickness of the upper electrode is enlarged in order to reduce the brightness gradient in a screen, the film thicknesses of the upper electrodes for a red pixel and a green pixel are enlarged without enlarging the film thickness of the upper electrode for a blue pixel. This makes it possible to reduce the brightness gradient as well as to suppress the light absorption of the upper electrode.

摘要： The strength of the whole OLED is increased by proposing a new method of fixing OLED panels. To address the problem, an OLED element is formed on a substrate, and a sealing substrate of a structure by which the substrate is sealed is fixed to a lower metallic frame via an elastic sheet. Silicon resin is preferably used as the sheet, and use of a sheet having a heat diffusion function based on radiation is more desirable.
