摘要： 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.
