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

This abstract first appeared for US patent application 18303741 titled 'LIGHT EMITTING DEVICE, MANUFACTURING METHOD OF LIGHT EMITTING DEVICE, DISPLAY DEVICE, PHOTOELECTRIC CONVERSION DEVICE, ELECTRONIC APPARATUS, ILLUMINATION DEVICE, MOVING BODY, AND WEARABLE DEVICE

Simplified Explanation

The patent application describes a light emitting device with arranged pixels.

  • Each pixel consists of an organic layer, a reflective layer, a first insulator, a transmission electrode, and a second insulator.
  • The second insulator covers the peripheral edge of the transmission electrode but has an opening to expose a part of it.
  • A groove is present between the transmission electrode and the reflective layer, and it extends through the first insulator.
  • The transmission electrode is electrically connected to the reflective layer within the groove.
  • The second insulator includes a recess portion that covers the groove.


Original Abstract Submitted

A light emitting device in which pixels are arranged is provided. Each of the pixels includes an organic layer including a light emitting layer, a reflective layer arranged between the main surface and the organic layer, a first insulator arranged between the reflective layer and the organic layer, a transmission electrode arranged between the first insulator and the organic layer, and a second insulator arranged so as to cover a peripheral edge portion of the transmission electrode while including an opening portion that exposes a part of the transmission electrode. A groove extending through the first insulator is provided between the peripheral edge portion of the transmission electrode and the reflective layer, the transmission electrode is electrically connected to the reflective layer in the groove, and the second insulator includes a recess portion in a portion covering the groove.
