Abstract: The present disclosure relates to an organic compound having the following structure, and an organic light emitting diode (OLED) and an organic light emitting device including the organic compound. Applying the organic compound into an emissive layer makes the OLED and the organic light emitting device lower their driving voltage, improves their luminous efficiency and color purity.

Abstract: A lens assembly including an incident side on which light is incident and an exit side opposite to the incident side, includes: a first polarization layer disposed adjacent to the incident side; a second polarization layer disposed between the first polarization layer and the exit side; a phase retardation layer disposed between the first polarization layer and the second polarization layer. The phase retardation layer has a first phase retardation refractive index along a first direction, has a second phase retardation refractive index equal to the first phase retardation refractive index along a second direction, and has a third phase retardation refractive index along a third direction perpendicular to the first direction and the second direction, and the first phase retardation refractive index and the second phase retardation refractive index are different from the third phase retardation refractive index.

Abstract: A display device includes a substrate. A light emitting element layer is disposed on the substrate. The light emitting element layer includes a plurality of emission areas. Each of the emission areas comprises a light emitting element emitting light. A thin film encapsulation layer is on the light emitting element layer. The thin film encapsulation layer comprises a first inorganic encapsulation film, a first organic encapsulation film on the first inorganic encapsulation film, and a second inorganic encapsulation film on the first organic encapsulation film. A light control layer includes a first light blocking layer disposed on the thin film encapsulation layer and having a first opening, and a first light transmitting layer disposed on the first light blocking layer. The first light transmitting layer includes an organic layer. A refractive index of the first light transmitting layer is greater than a refractive index of the first organic encapsulation film.

Abstract: A display panel includes a first substrate including a display area, in which a plurality of pixel areas is arranged, and a non-display area around the display area, a second substrate disposed opposite to the first substrate, a light emitting array disposed on the first substrate and including a plurality of light emitting elements corresponding to the plurality of pixel areas, a sealing layer disposed in the non-display area between the first substrate and the second substrate and bonding the first substrate and the second substrate to each other, a vacuum layer sealed by the sealing layer and defined between the light emitting array and the second substrate, and a reflection adjustment layer disposed on the second substrate and absorbing a portion of external light, where the reflection adjustment layer includes a plurality of protrusions protruding toward the light emitting array and exposed to the vacuum layer.
