Description

[0001] Cross References to Related Applications [0002] This application claims priority and benefit from Korean Patent Application No. 10-2018-0001255 filed on January 4, 2018, which is hereby incorporated by reference for all purposes as if fully set forth herein. technical field [0003] Exemplary embodiments / execution modes of the present application relate to an organic electroluminescent device and a monoamine compound for an organic electroluminescent device. Background technique [0004] Researchers are actively conducting development of organic electroluminescent display devices as image display devices. Unlike a liquid crystal display device, an organic electroluminescent display device is a self-luminous display device in which holes and electrons injected from a first electrode and a second electrode are recombined in a light emitting layer. A light emitting material including an organic compound in the light emitting layer emits light to display an image. [...
