Abstract: Provided are an organic electroluminescence device, which shows high luminous efficiency, is free of any pixel defect, and has a long lifetime, and a material for an organic electroluminescence device for realizing the device. The material for an organic electroluminescence device is a compound having a ?-conjugated heteroacene skeleton crosslinked with a carbon atom, nitrogen atom, oxygen atom, or sulfur atom. The organic electroluminescence device has one or more organic thin film layers including a light emitting layer between a cathode and an anode, and at least one layer of the organic thin film layers contains the material for an organic electroluminescence device.
Abstract: Disclosed are an organometallic complex, and an organic electroluminescence device and a display device including the same. The organometallic complex is represented by the following Chemical Formula 1. The definition of the above Chemical Formula 1 is the same as described in the detailed description.
