  • Patent number: 7557898
    Abstract: A substrate gap adjusting device adjusts a gap between first and second substrates in a composite substrate. In the substrate gap adjusting device, the composite substrate includes 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.
