Flexible light-emitting device, and method and device for manufacturing same

An apparatus for producing a flexible light-emitting device comprising:

• a stage for supporting a flexible light-emitting device supporting substrate, the flexible light-emitting device supporting substrate including a glass base and a plastic film provided on the glass base;
• a polisher head configured to approach a selected region of a surface of the plastic film and polish the region so that a polish recess is formed in the surface;
• and
• a repair head for supplying a liquid material to the polish recess formed in the surface of the plastic film and heating the liquid material locally, thereby forming a sintered layer from the liquid material, the repair head including an infrared light source,
• wherein the sintered layer is a metal oxide layer, and
• the flexible light-emitting device is a flexible lighting device.
