Abstract
(EN)
A flexible surface lighting device is disclosed. The flexible surface lighting device comprises: a flexible substrate comprising an upper insulation film, a lower insulation film, and a metal thin film layer interposed between the upper insulation film and the lower insulation film; a plurality of micro LED chips arranged in a two-dimensional manner on the upper surface of the flexible substrate; and a flexible light-transmitting resin part formed on the upper surface of the flexible substrate so as to cover the upper surfaces and side surfaces of the micro LED chips, wherein the flexible substrate comprises, in the upper insulation film, a white reflective layer in contact with the light-transmitting resin part.
