ABSTRACT:
There is provided a method for manufacturing a light emitting device in which no copy-in is caused in the case of a light emitting device having a glossy cathode. An uneven portion is formed on the surface of a cathode which is in contact with an organic layer in a pixel portion, and incident light is reflected in all directions. An insulating film having a high light absorption property is formed in a driver circuit portion, and the copy-in becomes invisible to the observer.
