DISPLAY DEVICE, ELECTRONIC DEVICE, AND METHOD OF MANUFACTURING DISPLAY DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18246156 titled 'DISPLAY DEVICE, ELECTRONIC DEVICE, AND METHOD OF MANUFACTURING DISPLAY DEVICE
Simplified Explanation
The patent application describes a display device with improved light extraction efficiency and viewing angle characteristics.
- The display device includes a substrate, a light emitting element, and a sealing layer.
- The light emitting element is attached to the substrate.
- The sealing layer seals the light emitting element.
- The light emitting surface of the light emitting element has an uneven portion with concave and convex portions.
- A low refractive index portion is formed at the periphery of the sealing layer above the light emitting element.
- The refractive index of the low refractive index portion is lower than that of the sealing layer.
Original Abstract Submitted
A display device, a method of manufacturing a display device, and an electronic device excellent in light extraction efficiency and viewing angle characteristic are provided. A display device includes: a substrate; a light emitting element attached to the substrate; and a sealing layer that seals the light emitting element, in which an uneven portion having a plurality of concave portions and a plurality of convex portions is provided on a light emitting surface of the light emitting element, and a low refractive index portion having a refractive index lower than that of the sealing layer is formed at a periphery of an immediately above portion above the light emitting element in the sealing layer.
