Abstract
An electroluminescent display panel has pixel circuits for an active matrix driving system. At least one of the pixel circuits has a thin-film transistor in which a portion of a pattern of a metal wiring material above a channel layer of the thin-film transistor is disposed to shield the channel region of the thin-film transistor.
Claims2
A display panel comprising;
- (i) a substrate,
- (ii) a stacked structure disposed on the substrate, the stacked structure including, in this order:
- (ii-a) a first molybdenum layer,
- (ii-b) a first insulating layer,
- (ii-c) a polysilicon layer to form a source/drain region and a channel region of the sampling transistor,
- (ii-d) a second insulating layer,
- (ii-e) a second molybdenum layer electrically connected directly to the first molybdenum layer to form a gate electrode of the sampling transistor, and
- (ii-f) a third insulating layer,
- (iii) a light-emitting element disposed on the stacked structure, the light-emitting element including:
- (iii-a) a metallic anode electrode disposed on the third insulating layer,
- (iii-b) an organic layer disposed on the metallic anode electrode, and
- (iii-c) a transparent cathode electrode disposed on the organic layer,
- wherein a gate electrode of a driving transistor is electrically connected to the polysilicon layer and a first electrode of a storage capacitor, and
- a second electrode of the storage capacitor is electrically connected directly to the metallic anode electrode and is electrically connected directly to a source/drain region of the driving transistor.
