Patent ID: 8652859

Claim:
A method for manufacturing a light-emitting device comprising: providing a substrate, wherein a hemispherical lens is provided over a first surface of the substrate; forming a light-emitting element over a second surface of the substrate, wherein the light-emitting element includes a light-emitting organic compound between a pair of electrodes; forming a sealing member covering the light-emitting element; detecting a defective portion of the light-emitting element; and insulating the defective portion by irradiation with a laser beam through the hemispherical lens in the case where the defective portion is detected, wherein an energy density of the laser beam is greater than or equal to 1 kW/cm 2 and less than or equal to 10 MW/cm 2 or greater than or equal to 1 μJ/cm 2 and less than or equal to 10 mJ/cm 2 , wherein a diameter of the hemispherical lens is greater than or equal to 0.2 mm and less than or equal to 20 mm, and wherein a beam diameter of the laser beam is greater than or equal to 0.1 mm and less than or equal to the diameter of the hemispherical lens.
