The invention provides a small-sized liquid crystal display in which a frame region of an outer peripheral portion of a display region is made small without any light leak at peripheral portion of the display region of a liquid crystal display panel. The joint has a first joint part with a spherical head and a second joint part with a spherical seat for the head. The implantable bioprosthesis is adapted to sufficiently degrade upon exposure to a cell or an enzyme to permit an expansion of the implantable bioprosthesis.
