  • Patent number: 7206113
    Abstract: The invention provides an electro-optical device which displays image of high quality without forming poorly oriented regions that stem from the presence of pole-like spacers, yet achieving a high numerical aperture. Pole-like spacers according to the invention are provided on at least either one of a first substrate and a second substrate holding a liquid crystal layer and on the to-be-provided surface of the one substrate on the side facing the liquid crystal layer, the pole-like spacers having, at the roots thereof, a slope portion with a surface smoothly connecting to the to-be-provided surface.

  • Patent number: 6906841
    Abstract: The invention provides a color filter substrate in which light leakage ascribable to the gap of colored layers, etc. are reduced or prevented from occurring, and which is capable of displaying a color image of high quality, and a method of manufacturing the same. A color filter substrate which has pixel portions arrayed in the shape of a matrix on a substrate includes a first colored layer which is formed at parts in either of a transmission region and a reflection region adjacent to each other within each of the pixel portions, and a second colored layer which is formed in both the regions and on the whole surfaces thereof except the formation region of the first colored layer.

  • Patent number: 6829070
    Abstract: The invention provides an electro-optic device capable of keeping the cell gap constant or substantially constant throughout the substrate surface regardless of the existence of a liquid crystal inlet. The electro-optic device of the invention has a TFT array substrate and an opposite substrate formed to sandwich an electro-optic material; a liquid crystal inlet to communicate the clearance sandwiched between the substrates with the exterior; and a plurality of columnar spacers scattered within the surfaces in parallel to the substrates to keep the clearance between the substrates at a predetermined thickness, the columnar spacers being disposed more densely in the vicinity of the liquid crystal inlet and more sparsely in the other area within the surfaces.

  • Patent number: 4911099
    Abstract: A painting system for painting a finned-tube heat exchanger suspended from a conveyor line so as to be conveyed thereby, comprises: (i) means for spraying on said heat exchanger with a water-soluble paint; (ii) means for air-blowing on said heat exchanger; and (iii) means for electrostatic spraying on said heat exchanger with a solvent-soluble paint. Each of spray nozzle assemblies and air-blow nozzle assemblies of said means issues paint spray or air blow to fins of said heat exchanger in a direction parallel to said fins. This painting system further comprises a scraper means for recovering said water-soluble paint sprayed and reached a wall member during spraying and air blow.
