  • Patent number: 8163126
    Abstract: Disclosed is a film sticking device that sticks a first film substrate and a second film substrate together on a curved-surface shape. The film sticking device includes a mold having a curved attachment surface formed into a desired curved-surface shape; an attracting and holding unit capable of relatively moving on the curved attachment surface and having plural vacuum chambers on which an attracting surface for attracting and holding the second film substrate is provided; and a suctioning unit capable of separately applying suction processing to the plural vacuum chambers. The suctioning unit starts, as the attracting and holding unit moves, the suction processing of the vacuum chamber corresponding to a position opposing the second film substrate and sequentially stops, as the second film substrate is stuck to the first film substrate, the suction processing of the vacuum chamber corresponding to the stuck second film substrate.
