Title:
COLOR CONVERSION FILM AND MULTICOLOR EMISSION ORGANIC EL DEVICE INCLUDING COLOR CONVERSION FILM
Document Type and Number:
WIPO Patent Application WO/2010/084587
Kind Code:
A1
Abstract:
Disclosed is a color conversion film for absorbing light from an organic EL light emitting portion emitting blue-green light and converting the absorbed light into visible light of longer wavelength. The color conversion film is composed of two kinds of pigments, namely a first pigment for absorbing light incident on the color conversion film and moving energy thereof to a second pigment, and a second pigment for receiving the energy from the first pigment and radiating light. The first pigment is a macromolecular pigment having an average molecular weight of 1,000-1,000,000. A multicolor emission organic EL device including a color conversion film of such a structure can achieve excellent conversion efficiency without increasing the thickness of the color conversion film like a conventional device of binder resin system.
