摘要： The organic photoelectric conversion element according to the invention has enhanced the light-absorbing property by incorporating two or more kinds of electron donating organic materials 4a and 4b in the photoelectric conversion region 14. With such measure, it has become possible to efficiently absorb the incident light and enhance the photoelectric conversion characteristic. In addition, a light-to-light conversion material 7 is incorporated in the photoelectric conversion region, too. With this measure, even the light of such a wavelength that an electron donating organic material cannot inherently absorb comes to be absorbed since the light-to-light conversion material 7 converts the wavelength, thus enabling the light to be utilized for carrier generation. Accordingly, an organic photoelectric conversion element with a high conversion efficiency can be obtained.

摘要： The invention presents an organic electroluminescence element excellent in long-term durability and reliability, a manufacturing method excellent in mass producibility, and a display device using the organic electroluminescence element. Accordingly, to prevent growth of dark spots in the luminous layer by completely shutting off invasion of moisture or oxygen into an anode or an organic thin film layer, a shield material is adhered to an element by using low melting glass or low melting solder. To fuse the low melting glass or low melting solder used for this purposes, laser or ultrasonic wave is used. The surface of the element is sealed with a protective film in a film thickness of 3 microns to 30 microns, or a protective film composed of two-layer laminate film of insulating compound layer andmetal film. According to these inventions, a highly reliable organic electroluminescence element small in changes in the time course suchas growth of dark sports and lowering of luminance is obtained.
