Document Type and Number:

WIPO Patent Application WO/2022/137539

Kind Code:

A1

Abstract:

The present invention provides a light emitting device that comprises: an anode; a cathode; a light emitting layer disposed between the anode and the cathode; a first electrode disposed to be able to generate a second electric field in the light emitting layer in cooperation with one of the anode and the cathode, the second electric field causing the total electric field generated in the light emitting layer to become close to zero, and the total electric field including a first electric field generated in the light emitting layer between the anode and the cathode; and a first insulating film that surrounds the first electrode in a cross-sectional view across the anode, the cathode, and the light emitting layer.
