Light emitting device

Abstract

A light emitting device includes a flexible substrate, a light emitting element, a conductive connecting material, and a holding member. The flexible substrate includes a flexible base and a wire arranged on the flexible base. The light emitting element is mounted on the substrate. The conductive connecting material connects the light emitting element to the wire. The holding member surrounds a region on the substrate including the light emitting element and the conductive connecting material, on a surface of the substrate on which the light emitting element is mounted. The holding member is arranged adjacent to the wire. The holding member includes a first region arranged on an inner side of the holding member, and having higher rigidity than rigidity of the flexible base, and a second region arranged adjacent to the first region outside the first region, and having lower rigidity than rigidity of the first region.
