Abstract:
1. A light emitting device comprising: a substrate; a thin film transistor over the substrate; a first insulating film comprising an organic resin over the thin film transistor; a second insulating film formed over the first insulating film, the second insulating film comprising at least one selected from the group consisting of silicon nitride, aluminum oxide, aluminum nitride, nitrated aluminum oxide and diamond like carbon; a first electrode electrically connected to the thin film transistor, over the second insulating film; a bank over the second insulating film, the bank covering an edge of the first electrode; an EL layer disposed adjacent to a side edge of the bank, over the first electrode; a second electrode covering the bank and the EL layer; and a third insulating film covering the second electrode, wherein the EL layer does not extend beyond the side edge of the bank, and wherein the third insulating film comprises silicon nitride oxide film or a silicon nitride film.
