LIGHT-EMITTING APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18578120 titled 'LIGHT-EMITTING APPARATUS
The abstract describes a high-resolution light-emitting apparatus that emits blue light with a high blue index. The apparatus includes pixel electrodes A and B, a common electrode, EL layers A and B sandwiched between the pixel electrodes and the common electrode, and an insulating layer positioned between the common electrode and each EL layer.
- Pixel electrodes A and B are adjacent to each other, with EL layers A and B sandwiched between them and the common electrode.
- The insulating layer has opening portions overlapping with each pixel electrode.
- EL layer A contains a light-emitting substance that emits blue light and is in contact with pixel electrode A.
- EL layer B is in contact with pixel electrode B.
- EL layer A is in contact with the common electrode in the opening portion, as is EL layer B.
Potential Applications: - High-resolution displays - Medical devices - Automotive lighting systems

Original Abstract Submitted
A high-resolution light-emitting apparatus that emits blue light with a high blue index is provided. The light-emitting apparatus includes a pixel electrode A; a pixel electrode B adjacent to the pixel electrode A; a common electrode; an EL layer A sandwiched between the pixel electrode A and the common electrode; an EL layer B sandwiched between the pixel electrode B and the common electrode; and an insulating layer positioned between the common electrode and each of the EL layer A and the EL layer B. The insulating layer has an opening portion A overlapping with the pixel electrode A and an opening portion B overlapping with the pixel electrode B. The EL layer A includes a light-emitting layer A. The light-emitting layer A contains a light-emitting substance A. The light-emitting substance A emits blue light. The EL layer A is in contact with the pixel electrode A. The EL layer B is in contact with the pixel electrode B. The EL layer A is in contact with the common electrode in the opening portion A. The EL layer B is in contact with the common electrode in the opening portion B.
