摘要：
An organic electroluminescence device comprising an anode, an organic hole transport layer, an organic emission layer and a cathode layered in this order on a substrate, or, optionally, comprising an additional electron transport layer between the organic emission layer and the cathode, wherein the organic emission layer comprises a benzoxazinone derivative represented by formula (1), wherein R.sup.1 is a specific acyl group or sulfonyl group, and R.sup.2 and R.sup.3 are specific substituents.
