Abstract:
1. A substrate gap adjusting device which adjusts a gap between first and second substrates in a composite substrate, the composite substrate including: the first substrate; the second substrate that is oppositely bonded to the first substrate through a sealant, the second substrate having a smaller area than the first substrate; and liquid crystal that is injected into a space surrounded by the first substrate, the second substrate, and the sealant, the substrate gap adjusting device comprising: a first base that has a mounting section; a ring-shaped support member that is mounted on the mounting section and that comes in contact with a second surface out of two surfaces of the first substrate so as to support the composite substrate, the second surface being opposite to a first surface on which the second substrate is bonded; more than two substrate pressing sections that have a movable range in a normal direction that is normal to a plane defined by the support member and that come in contact with the first substrate at a circumferential edge of the first surface; and external force applying sections that independently transmit force to the corresponding substrate pressing sections to displace the substrate pressing sections independently from each other within the movable range, wherein the circumferential edge of the first surface is positioned at an outer side of the support member, as seen from the normal direction.
