ORGANIC COMPOUND AND ORGANIC LIGHT-EMITTING ELEMENT COMPRISING SAME

Title:

ORGANIC COMPOUND AND ORGANIC LIGHT-EMITTING ELEMENT COMPRISING SAME

Document Type and Number:

WIPO Patent Application WO/2023/182754

Kind Code:

A1

Abstract:

The present invention relates to an organic compound that can enhance the light efficiency of light extracted to the outside of an organic light-emitting element due to having a low refractive index, and thus can be effectively utilized as a material for a light efficiency improvement layer provided in the organic light-emitting element. The compound according to the present invention can be employed in the light efficiency improvement layer to achieve a high-efficiency, long-lifespan organic light-emitting element having improved light-emitting efficiency, color purity, and lifespan characteristics, as well as low-voltage driving characteristics, and thus can be effectively used in various lighting and display elements.
