LIGHT-EMITTING ELEMENT AND DISPLAY DEVICE INCLUDING THE SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 18125842 titled 'LIGHT-EMITTING ELEMENT AND DISPLAY DEVICE INCLUDING THE SAME
Simplified Explanation
The patent application describes a light-emitting element with specific structural features.
- The light-emitting element includes a first electrode and an insulating layer with multiple sub-insulating layers.
- The sub-insulating layers are spaced apart from each other and have a bar shape extending in a perpendicular direction.
- A hole transport region is placed on the insulating layer, consisting of a contact portion in contact with the first electrode and a non-contact portion.
- A light-emitting layer is positioned on the hole transport region, with a light-emitting portion overlapping the contact portion and a diffusion portion overlapping the non-contact portion.
- An electron transport region is located on the light-emitting layer.
- Finally, a second electrode is placed on the electron transport region.
Original Abstract Submitted
A light-emitting element includes a first electrode, an insulating layer including a plurality of sub-insulating layers disposed on the first electrode, spaced apart from each other by a distance in the first direction, and having a bar shape extending in the second direction substantially perpendicular to the first direction, a hole transport region disposed on the insulating layer and including a contact portion in contact with the first electrode, and a non-contact portion not contacting the first electrode, a light-emitting layer disposed on the hole transport region and including a light-emitting portion overlapping the contact portion in a plan view, and a diffusion portion overlapping the non-contact portion in a plan view, an electron transport region disposed on the light-emitting layer, and a second electrode disposed on the electron transport region.
