LIGHT EMITTING DEVICE, MANUFACTURING METHOD THEREOF, DISPLAY DEVICE, PHOTOELECTRIC CONVERSION DEVICE, ELECTRONIC APPARATUS, ILLUMINATION DEVICE, AND MOVING BODY - A simplified explanation of the abstract

This abstract first appeared for US patent application 18303751 titled 'LIGHT EMITTING DEVICE, MANUFACTURING METHOD THEREOF, DISPLAY DEVICE, PHOTOELECTRIC CONVERSION DEVICE, ELECTRONIC APPARATUS, ILLUMINATION DEVICE, AND MOVING BODY

Simplified Explanation

The patent application describes a light emitting device with multiple electrodes, an organic layer, a second electrode, and an insulating layer.

  • The device has a structure that allows for efficient light emission.
  • The first electrodes are separated by an insulating layer.
  • The upper surface of each electrode has an inner region in contact with the organic layer and an outer region in contact with the insulating layer.
  • The insulating layer has an opening that defines the inner region and a step that overlaps the outer region.
  • This design helps improve the performance and reliability of the light emitting device.


Original Abstract Submitted

A light emitting device includes a plurality of first electrodes, an organic layer located above the plurality of first electrodes and including a light emitting layer, a second electrode located above the organic layer, and an insulating layer that separates the plurality of first electrodes from each other. An upper surface of each of the plurality of first electrodes includes an inner region in contact with the organic layer, and an outer region in contact with the insulating layer. The insulating layer includes an opening that defines the inner region, and a step located at a position away from the opening and overlapping the outer region.
