Description

BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] The present invention relates to a platinum complex compound useful as a light-emitting material, and an organic electroluminescence device (hereinafter also referred to as “an organic EL device) using the same.

[0003] 2. Description of the Related Art

[0004] Organic electroluminescent devices are capable of obtaining emission of high luminance by low voltage driving, and actively researched and developed in recent years. An organic EL device generally consists of a pair of electrodes with an organic compound layer including a light-emitting layer, and electrons injected from the cathode and holes injected from the anode are recombined in the light-emitting layer, and generated energy of exciton is used for emission.

[0005] The increase in efficiency of the devices has been advanced by the use of phosphorescent materials. Iridium complexes and platinum complexes are known as the phosphorescent materials, and a platinum comple...
