Abstract:
1. A device comprising: a semiconductor film formed over an insulating surface; a first insulating film formed over the semiconductor film; a gate electrode formed over the first insulating film; a second insulating film formed over the gate electrode wherein the second insulating film has a contact hole; one of a source wiring and a drain wiring formed over the second insulating film wherein one of the source wiring and the drain wiring is electrically connected to the semiconductor film through the contact hole of the second insulating film; a third insulating film formed over one of the source wiring and the drain wiring; a leveling film formed over the third insulating film; a fourth insulating film formed over the leveling film; and an electroluminescence element formed over the leveling film, the electroluminescence element comprising a first electrode, an electroluminescence layer formed over the first electrode and a second electrode formed over the electroluminescence layer, wherein the first insulating film has a thickness within a range from 10 nm to 200 nm, wherein the second insulating film has a thickness within a range from 400 nm to 1.5 μm, wherein the third insulating film has a thickness within a range from 10 nm to 1 μm, and wherein the fourth insulating film has a thickness within a range from 5 nm to 1 μm.
