Zusammenfassung:	A flexible surface lighting device is disclosed. The flexible surface lighting device includes: a flexible substrate including an upper insulating film, a lower insulating film, and a thin metal layer interposed between the upper and lower insulating films; a plurality of micro-LED chips two-dimensionally arrayed on the top surface of the flexible substrate; and a flexible light-transmitting resin part disposed on the top surface of the flexible substrate to cover the top and side surfaces of the micro-LED chips. The flexible substrate includes a white reflective layer in contact with the light-transmitting resin part on the upper insulating film.
