Abstract

A mounting structure includes a substrate, a first terminal, a first flexible circuit board, and a second terminal. The first terminal is arranged in a first region of a first face of the substrate. The first flexible circuit board is connected to the first terminal through an anisotropic conductive film. The second terminal is arranged in a second region of a second face, which is a rear face relative to the first face of the substrate, wherein the second region does not overlap the first region in plan view. A region of the second face of the substrate, which overlaps the first region in plan view, is formed to be a smooth face.
