1. A method of manufacturing a light emitting device comprising:
forming a thin film transistor on an insulator;
forming an interlayer insulating film on the thin film transistor;
forming a first insulating film on the interlayer insulating film by plasma treatment;
forming an anode on the first insulating film;
forming a wiring for electrically connecting the thin film transistor to the anode;
forming a bank over the first insulating film, edge portions of the anode, and the wiring;
forming a second insulating film on the anode and the bank;
forming an organic compound layer over the anode with the second insulating film interposed therebetween; and
forming a cathode on the organic compound layer,
wherein the first insulating film is a cured film and comprises one or more kinds of gas elements selected from the group consisting of hydrogen, nitrogen, halogenated carbon, hydrogen fluoride, and rare gas.
