  • Patent number: 7092066
    Abstract: An apparatus for manufacturing a liquid crystal display is provided with a first supporter for supporting a first substrate with the state of restraining the displacement in a surface direction of the first substrate on a first surface plate, a second supporter for supporting a second substrate with the state of restraining the displacement in a surface direction of the second substrate on a second surface plate, a pressurized for press-welding the first and second substrates by pressing the first and second surface plates, and a position-aligning mechanism for performing an alignment between the first and second substrates while the pressing means presses the first and second surface plates.

  • Patent number: 6190456
    Abstract: A spacer spraying device for spraying a powdery spacer onto, e.g., a substrate for an LCD (Liquid Crystal Display) is disclosed. When the device sprays the spacer onto the top of the substrate in a spray chamber, it prevents the spacer from depositing on the inner side walls and top wall of the chamber and dropping in the form of cohered masses onto the substrate.

  • Patent number: 6155426
    Abstract: There is provided a cassette case for holding a plurality of substrates therein, including a cassette case for holding a plurality of substrates therein, including (a) a three-dimensional, hollow frame, and (b) a pair of substrate support members spaced away from each other and carried at the frame with at least one substrate being supported therebetween in the frame. The substrate support members are fixedly carried at the frame at one of longitudinal ends thereof, and at the other of the longitudinal ends thereof so that so that the members are able to expand or contract in a length-wise direction thereof. The above mentioned cassette case ensures that even if the substrate support members thermally expand when the cassette case is thermally treated, there is nothing which obstructs thermal expansion of the substrate support members. Thus, it is possible to eliminate deformation of the substrate support members caused by obstruction to thermal expansion of the substrate support members.

  • Patent number: 5684557
    Abstract: In an apparatus for adhering a polarizer to an LCD (Liquid Crystal Display) panel, a set plate for holding the panel thereon by suction is formed with a plurality of channels on the surface thereof. A discharge bar adjoins the set plate and blows air under pressure into the channels. When the panel is laid on or separated from the set plate, the air dissipates static electricity. This reduces electrostatic charge deposited on the panel and thereby reduces the electrostatic breakdown of the panel.
