Patent ID: 6852997

Claim:
A light emitting device comprising: a first insulating film comprising silicon nitride or silicon oxynitride; a semiconductor layer over the first insulating film; a gate insulating film over the semiconductor layer; a gate electrode over the gate insulating film; a second insulating film comprising silicon nitride or silicon oxynitride over the gate electrode; a third insulating film comprising an inorganic insulating material selected from the group consisting of silicon nitride, silicon oxynitride, aluminum oxynitride, aluminum oxide and aluminum nitride over the second insulating film; a layer comprising an organic resin over the third insulating film; a partitioning layer comprising an inorganic insulating material selected from the group consisting of silicon nitride, silicon oxynitride, aluminum oxynitride, aluminum oxide and aluminum nitride over the layer comprising an organic resin; a fourth insulating film comprising an inorganic insulating material selected from the group consisting of silicon nitride, silicon oxynitride, aluminum oxynitride, aluminum oxide and aluminum nitride over the third insulating film and the partitioning layer; a light emitting layer comprising an organic compound surrounded by the third insulating film, the fourth insulating film and the partitioning layer; and a cathode contacting the light emitting layer.
