<P>PROBLEM TO BE SOLVED: To provide a display device in which chromaticity shifting and variations in light-emission luminance (light-emitting intensity) are suppressed, in which there is no bleeding or blurrs of images, and which is superior in display characteristics, and to provide a manufacturing method for the display device. <P>SOLUTION: The organic EL element has a device structure in which an reflecting metal O composed of a metal material, having light-reflecting characteristics (for example, silver (Ag)) or the like is the lowermost layer, and on its upper layer; a thick membrane layer F of a membrane thickness df constituted of an insulating material having light transmissive characteristics, a transparent anode electrode 1 of the membrane thickness da constituted of a transparent electrode material such as an ITO; an EL light-emitting layer 2 of the membrane thickness Xp+Xq which is a light-emitting function layer; a transparent cathode electrode 3 of the membrane thickness dc constituted of the transparent electrode material, such as the ITO; and a passivation membrane 4 constituted of a silicon nitride (SiN) are laminated and formed sequentially. <P>COPYRIGHT: (C)2009,JPO&INPIT |
