Patent ID: 11961842
Assignee: SEMICONDUCTOR ENERGY LABORATORY CO., LTD.
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 2:
3. A light-emitting device comprising:
a driving transistor;
a light-emitting element electrically connected to the driving transistor;
a color filter layer;
an insulating layer; and
a resin layer,
wherein the light-emitting element comprises:
a first electrode;
a light-emitting layer over the first electrode; and
a second electrode over the light-emitting layer,

wherein light emitted from the light-emitting element is configured to pass through the first electrode and the color filter layer,
wherein the insulating layer is below the color filter layer,
wherein the resin layer is over the color filter layer,
wherein the first electrode and one of a source electrode and a drain electrode of the driving transistor are electrically connected to each other in a contact hole provided in the insulating layer,
wherein an upper surface of the insulating layer is in contact with a bottom surface of the resin layer in a peripheral region of the contact hole, and
wherein the driving transistor comprises:
an oxide semiconductor layer comprising a crystal with a grain size of greater than or equal to 1 nm and less than or equal to 20 nm at least on an upper surface side;
a first gate electrode below the oxide semiconductor layer; and
a second gate electrode over the oxide semiconductor layer.
