Abstract: A substrate includes a first base, a first trace, a first organic layer, a first inorganic layer, and a second trace. The first organic layer includes at least one first via hole, and a first via hole exposes a portion of the first trace. The first inorganic layer includes at least one second via hole. On the first base, an orthographic projection of an edge of an opening of a second via hole proximate to the first via hole is substantially coincident with an orthographic projection of an edge of an opening of the first via hole proximate to the second via hole. The first and second via holes are communicated to form a connecting hole to connect the first and second traces. A ratio of a depth of the connecting hole to a maximum radial dimension of the connecting hole ranges from 1:1 to 1:2, inclusive.
