摘要： A color conversion film is disclosed 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.

摘要： The present invention provides a high-efficiency organic EL device that can be fabricated by a simple process and that can prevent color shift arising from variations in film thickness. The organic EL light-emitting device includes a plurality of independent light-emitting elements that constitute first, second, and third emission color subpixels. The light-emitting elements constituting the first emission color subpixels and the second emission color subpixels have a semitransparent reflective layer between a transparent substrate and a transparent electrode, and this semitransparent reflective layer is configured so as to function with the reflective electrode as a resonator for the light of the emission colors. The light-emitting elements constituting the third emission color subpixels additionally have a color conversion layer between the transparent substrate and the transparent electrode.

摘要： The organic thin-film light-emitting device includes a substrate, a plurality of first electrodes arranged parallel on the substrate, an electroluminescent layer made of an organic material and formed on the first electrodes, a plurality of second electrodes formed on the electroluminescent layer, and an electrically insulating barrier wall. The barrier wall includes barrier wall lines disposed at gaps in an electrode pattern of the second electrodes, and barrier wall end lines connected to the barrier wall lines so that the barrier wall lines do not have ant free ends. Thus, peeling-off of the barrier wall lines as a shadow mask at their end is prevented.
