Abstract
Official abstract text for this publication.
The present invention relates to: a dopant for an organic optoelectronic device, represented by chemical formula 1; an organic optoelectronic device including the dopant; and a display device.
First claim
Opening claim text (preview).
The invention claimed is: 1. An organic optoelectronic device, comprising: an anode and a cathode facing each other, and a light emitting layer disposed between the anode and the cathode, the light emitting layer including: a host, and a dopant, the dopant being a compound of Group 1 [Grou 1′] wherein: the host is selected from the compound having a larger energy bandgap than the dopant, the dopant is included in an amount of 0.01 wt % to 40 wt % based on a total amount of the host and the dopant, provided that the dopant is included in a smaller amount than the host, 2. A display device comprising the organic optoelectronic device of claim 1 .
