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.

A method for arraying micro-LED chips is disclosed. The method includes preparing a chip carrier formed with a plurality of chip pockets whose internal pressure is reduced through a plurality of suction holes, capturing the micro-LED chips in the corresponding chip pockets such that the micro-LED chips are in close contact with the bottoms of the chip pockets, and placing the micro-LED chips captured in the chip pockets on a base body. Each of the chip pockets includes a slope through which an inlet having a larger width than the bottom is connected to the bottom. The distances between the centers of the adjacent micro-LED chips placed on the base body are the same as those between the centers of the corresponding chip pockets.
