  • Publication number: 20190378768
    Abstract: A display panel producing system for producing a display panel including a substrate on which films are laminated includes a measuring device, an ink-jet coating device, and a control device. The measuring device is configured to measure an uneven shape of a front face of the substrate in production. The ink-jet coating device is configured to apply a film formation material with an ink-jet technology to form the films on the substrate. The control device is configured to control the measuring device and the ink-jet coating device. The control device controls the measuring device to measure the uneven shape for formation of the films by the ink-jet coating device and to determine a control target for the formation of the films by the ink-jet coating device appropriate for the substrate on which measurement of the uneven shape is performed based on a result of the measurement.

  • Patent number: 7936439
    Abstract: A broad crystal display panel having a color filter substrate is supported by supporting nails and the middle portion of a supporting span is pressed by a loading bar. From this state, the supporting nails are removed to release the supporting, and subsequently the supporting nails are also removed to release the supporting the color filter substrate. While preventing the displacement between the color filter substrate and a TFT array substrate, the color filter substrate and the TFT array substrate can be stacked with a specified distance.

  • Patent number: 7038756
    Abstract: Disclosed are a fixing device and method of fixing substrate to provide holding means capable of surely fixing and positioning a sheet-like substrate even in vacuum, and to provide an operational mechanism thereof. A fixing device includes: a carrier plate for setting a glass substrate thereon; a claw for pressing the glass substrate set on the carrier plate, when the glass substrate is set thereon, by sandwiching the glass substrate from the periphery thereof; and an airbag having air sealed therein and expanding by lowering an external pressure. The claw is operated by using expansion of the airbag as power, thereby fixing the glass substrate.

  • Patent number: 6738125
    Abstract: It is an object of the invention to provide a liquid crystal display apparatus in which the cell gap is uniform and the display quality is high, and also a method for manufacturing the same. In the liquid crystal display apparatus, a color filter side substrate in which a protrusion is formed by a black mask, and a TFT side substrate in which a recess is formed by a resin film such as an orientation film are bonded together via dispersed spacers therebetween, and a liquid crystal is filled between the substrates. In the resin film such as an orientation film, patterning is performed except a portion which is opposed to the protrusion, thereby forming the recess in the TFT side substrate. The formation of the recess prevents the cell gap from being pushed up even when the dispersed spacers are placed on the protrusion. Even in the case where the substrates are not flat, therefore, the cell gap can be maintained uniform.
