Abstract:
A semiconductor device includes a thin film transistor including an oxide semiconductor layer and a wire connecting portion ( 201 ). The wire connecting portion ( 201 ) includes a lower electrically-conductive portion ( 3 t ) formed out of a same electrically-conductive film as the gate electrode, an insulating layer ( 15 ) having a contact hole (CH 2 ) through which at least a part of the lower electrically-conductive portion ( 3 t ) is exposed, and an upper electrically-conductive portion ( 19 t ), at least a part of which is provided inside the contact hole (CH 2 ). The insulating layer ( 15 ) includes the gate insulating layer ( 4 ), the protection layer ( 9 ) and the interlayer insulating layer ( 13 ). At a lateral wall of the contact hole, the gate insulating layer ( 4 ) includes an upper portion ( 41 ) and a lower portion ( 42 ) which is present on the substrate side of the upper portion ( 41 ), and when viewed in a normal direction of the substrate, a lateral surface of the lower portion ( 42 ) juts out from a lateral surface of the upper portion ( 41 ). The upper electrically-conductive portion ( 19 t ) is in contact with the lower electrically-conductive portion ( 3 t ) and the lateral surface and an upper surface of the lower portion ( 42 ) of the gate insulating layer ( 4 ) inside the contact hole.

Claim (Index 3):
The semiconductor device of  claim 1  wherein, at the lateral wall of the contact hole, the lateral surface of the upper portion of the gate insulating layer is in alignment with the lateral surface of the protection layer.
