Document Type and Number:
Japanese Patent JP4154869
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an organic EL element, which has high durability under high temperature environment. SOLUTION: An electron hole pouring layer is prepared between layers of a transparent electrode layer and an electron hole transportation layer of an organic electric field light-emitting device. This electron hole pouring layer contains a metal porphyrin derivative compound shown in the formula (1) (in the formula, M is central metal, such as copper), and a compound, such as a non-metal porphyrin derivative compound of the formula (2), which has smaller polarity than this metal porphyrin derivative compound, that is, has affinity with an electron hole transportation material, or the like, and has affinity with the metal porphyrin derivative compound.
