Abstract
A first substrate includes: a first base material including an insulating layer; and a partition wall disposed on the insulating layer. The insulating layer and the partition wall are formed of a resin material. The partition wall has a higher hardness than the insulating layer. A protective film that protects the insulating layer is disposed on a surface of the insulating layer. A portion of the protective film is located between the partition wall and the insulating layer.
