Abstract
The present invention relates to an organic compound and an organic light-emitting device comprising same. The organic compound is used in a light efficiency improving layer included in an organic light-emitting device to increase the light efficiency of the device so as to be able to implement excellent device characteristics such as low voltage driving, excellent color purity, and improved luminescence efficiency of the device. Same can be industrially and usefully used for various lighting and display devices.
