Abstract
A display device includes: a first substrate that includes a semiconductor material layer in which a transistor has been formed, the transistor driving a light-emitting part that is included in a pixel; and a second substrate that includes a predetermined circuit. The first substrate and the second substrate are stuck together in such a way that respective joint surfaces face each other. A pad opening is provided from a side of the first substrate to face a pad electrode that has been provided on a side of the respective joint surfaces, in such a way that the pad electrode is exposed on a bottom surface.
