Patent ID: 7354803

Claim:
A method for manufacturing a substrate conjugate, comprising: a step of joining a first substrate including a first functional device to a second substrate including a second functional device; a step of providing a protective layer on at least one of: a face of the first substrate on which the first functional device is placed; and a face of the second substrate on which the second functional device is placed; a step of forming an opening through the protective layer such that the opening is located at a position corresponding to a terminal section electrically connected to the one of the first and the second functional devices covered by the protective layer; a step of forming a bump in and on the opening to form an electrical connection on the terminal section; a step of providing a sealing layer on the protective layer, the sealing layer electrically connecting the first functional device to the second functional device and sealing the first substrate to the second substrate, wherein the protective layer prevents the one of the first functional device and the second functional device on which the protective layer is provided from contacting the sealing layer, the sealing layer including resin spheres each coated with a conductive layer thereon; a step of applying a pressure on the first substrate and the second substrate to simultaneously seal the first substrate and the second substrate and electrically connect the first functional device and the second functional device; and a step of crushing the resin spheres to electrically connect the first functional device and the second functional device when the first substrate and the second substrate are joined and sealed, wherein the bump extends out of the opening and into the sealing layer to electrically connect the first functional device to the second functional device, and the bump is connected to the terminal section of the one of the first and the second functional devices and located at a lateral distance from principal portions of the one of the first and the second functional devices along a longitudinal direction of the protective layer, wherein the first and the second functional devices form a display pixel and one of the first and the second functional devices comprises a thin film transistor formed through transfer.
