A light emitting device comprising:
- a plurality of lower electrodes arranged on a substrate;
- a bank insulating film configured to cover a peripheral portion of an upper surface of each lower electrode of the plurality of lower electrodes and expose a central portion of the upper surface;
- and
- a planarizing film arranged on at least the plurality of lower electrodes and the bank insulating film and formed of a cured product of a curable composition.
A manufacturing method of a light emitting device that comprises a plurality of lower electrodes arranged on a substrate, and a bank insulating film configured to cover a peripheral portion of an upper surface of each of the plurality of lower electrodes and expose a central portion of the upper surface, the method comprising:
- arranging a curable composition on a structure including at least the substrate, the plurality of lower electrodes, and the bank insulating film;
- bringing a superstrate into contact with the curable composition;
- forming a planarizing film formed of a cured product of the curable composition by curing the curable composition in a state in which the curable composition and the superstrate are in contact with each other;
- and
- separating the superstrate from the planarizing film.
