Patent ID: 10388676

Abstract:
An active matrix substrate (1001) includes a connecting portion (101). The connecting portion. (101) includes a lower conductive layer supported by a substrate; a first insulating layer formed so as to cover the lower conductive layer (2) and having a contact hole (6p) that exposes a part of the lower conductive layer (2); a bottom conductive film (4) that is disposed in the contact hole (6p) and covers at least a part of the exposed part of the lower conductive layer (2), the exposed part being exposed by the contact hole (6p); a second insulating layer (9) that is formed on the first insulating layer (6) and in the contact hole (6p), is in contact with the bottom conductive film (4) in the contact hole (6p), and has an opening (9p) that exposes a part of the bottom conductive film (4); and an upper conductive layer (8) that is disposed on the second insulating layer (9) and in the opening (9p) and is in contact with the bottom conductive film (4) in the opening (9p). The entire bottom conductive film (4) is located on the substrate side relative to the upper surface of the first insulating layer (6).
