Abstract

A light emitting device which can prevent bending of the substrate member. The light emitting device includes a flexible substrate member, a plurality of light emitting elements, two first sealing members, and a second sealing member. The two first sealing members are disposed in-line on the substrate member and arranged in the longitudinal direction. The second sealing member is arranged extending in the longitudinal direction on the substrate member, and is offset in a lateral direction from the two first sealing members. The second sealing member is further arranged to extend across a first gap formed between the two first sealing members when viewed from a lateral direction, and overlap at least a portion of each of the two first sealing members. The second sealing member comprises a resin having transparency to light.
