LIGHT EMITTING ELEMENT, METHOD FOR MANUFACTURING THE SAME, AND DISPLAY DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18348815 titled 'LIGHT EMITTING ELEMENT, METHOD FOR MANUFACTURING THE SAME, AND DISPLAY DEVICE
Simplified Explanation
The abstract describes a light emitting element with specific layers and electrodes for efficient light emission. Here are the key points:
- Light emitting element includes lower layer/interlayer insulation layer, light reflection layer, upper layer/interlayer insulation layer, first electrode, insulation film, organic layer with light emitting layer, and second electrode.
- A groove is formed in the upper layer/interlayer insulation layer in the edge region of the element, closed with the insulation film.
- The organic layer contains an organic light emitting material for light emission.
- Potential Applications:**
- Display devices
- Lighting applications
- Electronic signage
- Problems Solved:**
- Efficient light emission
- Improved light reflection
- Enhanced durability of the element
- Benefits:**
- Higher brightness
- Better energy efficiency
- Longer lifespan of the light emitting element
Original Abstract Submitted
A light emitting element, display device, and method of manufacture of the same are disclosed. In one example, a light emitting element includes a lower layer/interlayer insulation layer; a light reflection layer formed on the lower layer/interlayer insulation layer; an upper layer/interlayer insulation layer; a first electrode formed on the upper layer/interlayer insulation layer; an insulation film formed at least on a region of the upper layer/interlayer insulation layer where the first electrode is not formed; an organic layer formed over the insulation film from above the first electrode, the organic layer having a light emitting layer including an organic light emitting material; and a second electrode formed on the organic layer. A groove is formed in a portion of the upper layer/interlayer insulation layer located in an edge region of the light emitting element, and an upper portion of the groove is closed with the insulation film.
