1. An electronic device comprising:
a light emitting element;
an encapsulation layer disposed on the light emitting element, wherein the encapsulation layer includes a polymer having a molecular anisotropy greater than or equal to about 1.4; and
a sensor layer disposed on the encapsulation layer,
wherein 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.
