Abstract: An electronic device includes a light emitting element. An encapsulation layer is disposed on the light emitting element. The encapsulation layer includes a polymer having a molecular anisotropy greater than or equal to about 1.4. A sensor layer is disposed on the encapsulation layer. The molecular anisotropy is a ratio of a first absorbance of an infrared spectrum in an infrared spectroscopy when first polarized light that is polarized in a first direction perpendicular to a second direction is incident to the polymer to a second absorbance of an infrared spectrum in an infrared spectroscopy when second polarized light that is polarized in the second direction is incident to the polymer.

Abstract: A display device includes a base layer, a circuit layer, a light emitting element layer, and a thin film encapsulation layer. The base layer includes a display area and a non-display area. The circuit layer includes a plurality of insulating layers, at least one of which has an opening. The light emitting element layer includes a light emitting area overlapping the display area, a valley area overlapping the opening and having a concave shape, and a peak area overlapping the non-display area and being on the circuit layer. The thin film encapsulation layer includes an organic encapsulation layer that covers the light emitting area, the valley area, and at least a portion of the peak area.

Abstract: An emissive display device includes a substrate. A first electrode is disposed on the substrate. A pixel defining layer has a first opening exposing the first electrode. A second electrode is disposed on both the pixel defining layer and the first electrode. An encapsulation layer at least partially covers the second electrode. A light blocking layer is disposed on the encapsulation layer and has a second opening. A color filter is disposed on the light blocking layer. A scattering layer is disposed within the second opening of the light blocking layer and includes a plurality of scattering particles. Particle density of the scattering particles has a value of 1 ea/mm3 or more and 10 ea/mm3 or less, and a diameter of the scattering particles is 0.1 μm or more and 1.5 μm or less.
