ABSTRACT:
A light emitting device structure is provided so as to increase the amount of light which is taken out in a certain direction after emitted from a light emitting element, as well as a method of manufacturing this light emitting device. In the present invention, an upper end portion of an insulating material19that covers an end portion of a first electrode18is formed to have a curved surface having a radius of curvature, a second electrode23ais formed to have a slant face as going from its center portion toward its end portion along the curved surface. Light emitted from a light emitting layer having an organic material20that is formed on the second electrode23ais reflected at the slant face of the second electrode23ato increase the total amount of light taken out in the direction.
