COLOR CONVERSION FILM AND MULTICOLOR EMITTING ORGANIC ELECTROLUMINESCENT DEVICE COMPRISING COLOR CONVERSION |
摘要 |
<p>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.</p> |
