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.

Electronic device including organic-polymer encapsulation layer

A display device includes a display panel, an input sensor disposed on the display panel, and an upper layer structure disposed on the input sensor. The upper layer structure includes a dielectric constant control layer which controls a sensing sensitivity of the input sensor.

Display device having dielectric constant control layer

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.
