An object is to provide a method for manufacturing a lighting device, in which a problem of a short circuit between an upper electrode and a lower electrode of a light-emitting element is solved without reducing a light-emitting property of a normal portion of the light-emitting element to the utmost. In a light-emitting element including an upper electrode, an electroluminescent layer, and a lower electrode, a short-circuited portion that is undesirably formed between the upper electrode and the lower electrode is irradiated with a laser beam, whereby a region where the short-circuited portion is removed is formed, and then the region is filled with an insulating resin having a light-transmitting property. Thus, the problem of the short circuit between the upper electrode and the lower electrode is solved and yield of a lighting device is improved.
