Patent number: 8847219Abstract: A color conversion film that absorbs light from an organic electroluminescent part emitting blue-green light and converts the light to visible light at a longer wavelength. The color conversion film includes two different dyes. A first dye is a polymer dye with an average molecular weight of 1000 to 1,000,000 that absorbs light incident on the color conversion film and transfers the energy of the light to a second dye. The second dye is a dye that receives the energy from the first dye and emits light. With a multicolor-emitting, organic electroluminescent device including the color conversion film, it is possible to achieve excellent conversion efficiency without increasing the thickness of the color conversion film as in a conventional device using a binder resin. Such an organic electroluminescent device may include as well a pair of electrodes at least one of which is a transparent electrode, and an organic electroluminescent layer sandwiched between the electrodes.Type: GrantFiled: September 23, 2013Date of Patent: September 30, 2014Assignee: Sharp Kabushiki KaishaInventors: Toshio Hama, Masaru Nagai, Chong Li, Koji Kawaguchi, Yuko Nakamata, Naoyuki Kanai

Patent number: 8771030Abstract: This invention provides a method capable of fabricating, by simple manufacturing processes, a color conversion layer which realizes high-efficiency color conversion characteristics without greatly increasing the film thickness of the color conversion layer. Further, this invention provides a color conversion layer manufactured by this method, and an organic EL element which includes this color conversion layer. By means of a method in which a polymer material having a weight-average molecular weight in a specific range is brought into contact with a color conversion material layer, and the polymer material is caused to intrude into the color conversion layer by a diffusion phenomenon, concentration quenching in the color conversion layer can be suppressed, and the fluorescence quantum yield can be increased.Type: GrantFiled: August 19, 2009Date of Patent: July 8, 2014Assignee: Sharp Kabushiki KaishaInventor: Masaru Nagai
