Document Type and Number:
Japanese Patent JP4153694
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an organic EL element having high efficiency and a long life by efficiently using energy of both host elements in the singlet state of excitation and the triplet state of excitation. SOLUTION: This organic EL element has a host element composed of an anode 2, a cathode 6, and a π electron conjugated polymer having a carbon- fluoride bonding, which is disposed between the anode 2 and the cathode 6, and a polymer luminescent layer 4 containing a luminescent color matter element selected from a group comprising a transition metal complex and a normal chain-shaped π electron conjugated polymer.
