The present technique provides an electronic device, such as a flexible EL display device, including: first barrier film including a laminate of inorganic film including an inorganic material and polymer film including a polymer material; second barrier film including a laminate of inorganic film including an inorganic material and polymer film including a polymer material; and thin film transistor array device and light emitter both sealed with first and second barrier films. Polymer films each contain at least one type of nano fine particles selected from silica particles, Fe-based particles, montmorillonite particles, silica-coated particles, and zeolite particles, dispersed in the polymer material.
