Abstract
A light-emitting device according to embodiments of the invention includes a film having light transmissive property to visible light; a conductor layer formed on one surface of the film; and a light-emitting element having electrodes connected to the conductor layer via bumps protruding toward the film. The curvature of the film curved on the outer edge of a contact area of the conductor layer contacting the bumps is defined by a radius of a circle contacting the conductor layer at at least three points on the outer edge of the contact area, and the radius of this circle is 13 μm or larger.
