  • Patent number: 6275280
    Abstract: The present invention provides a liquid crystal display element substrate having spacers fixed in non-display regions on the liquid crystal display element substrate, where the load compression displacement of these spacers in terms of a compression stress of 0.5 to 0.6 GPa is from 0.001 to 1 &mgr;m/mN. Further, it provides a liquid crystal display device which is characterized in that, in a liquid crystal display device where a liquid crystal layer is held between two liquid crystal display element substrates, at least one of these liquid crystal display element substrates is an aforesaid liquid crystal display element substrate. As well as realizing a sufficient cell gap the present invention has the effect that, by maintaining a uniform cell gap within the screen, the problems of a lowering in the display quality due to change in the cell gap and the generation of bubbles at the time of low temperature are resolved.

  • Patent number: 6139639
    Abstract: A coating apparatus which comprises a feeding means to feed a coating liquid, a coating liquid applicator having a slot extending in one direction to discharge the coating liquid fed by the feeding means, and a conveying means to move at least either the coating liquid applicator or a substrate to be coated with the coating liquid relatively one to the other, comprising: (a) a first control means which comprises (a-1) a position detecting means to detect positions of the coating liquid applicator or the substrate which is moved by the conveying means, and (a-2) a controller capable of stopping the coating liquid applicator or the substrate which is moved by the conveying means at a position detected by the position detecting means such that a start-of-coating line of the substrate is in register with the slot of the coating liquid applicator and capable of starting the movement of the coating liquid applicator or the substrate which is stopped at the position; and (b) a second control means which comprises a
