1. A light-emitting device comprising:
a light-emitting unit comprising a light-emitting panel, a secondary battery, and a circuit; and
a first member with rubber elasticity,
wherein the light-emitting unit is sealed by the first member with rubber elasticity,
wherein the light-emitting panel and at least one of the secondary battery and the circuit overlap with each other when seen from a light-emitting surface of the light-emitting device,
wherein the first member with rubber elasticity comprises an uneven structure including a first projection and a second projection on a back side of the light-emitting surface of the light-emitting device, and
wherein the first projection and the second projection come in contact with each other when the light-emitting device is folded.
