  • Patent number: 10469692
    Abstract: A scanning exposure device includes a stage that supports a substrate, wherein a space is provided between a stage surface and the substrate; a light source unit that radiates light to a light irradiation area that extends in one direction above the substrate; and a scanning device that moves one or both of the stage and the light source unit relatively in a scanning direction that intersects the one direction. The scanning device is provided with an acceleration zone from a position in which the stage and the light source unit are at a standstill to a position in which the substrate supported by the stage enters the light irradiation area. The stage comprises a light shielding member that covers the space between the stage surface and the substrate at an end part of the stage.
    Type: Grant

  • Patent number: 9034541
    Abstract: The present invention provides a color filter substrate manufacturing method which can prevent the occurrence of color mixing between adjacent pixels despite of the use of an inkjet method, and which are unlikely to cause flicker when used for displays such as televisions.

  • Patent number: 8576360
    Abstract: The present invention provides a color filter substrate in which reduction in display qualities is suppressed even if color mixing is generated when a plurality of differently colored transparent layers are formed by a method using a liquid material, such as an ink jet method, and to provide a liquid crystal display panel and a liquid crystal display device each including the color filter substrate. The color filter substrate of the present invention comprises a plurality of color display units, each of the color display units including four or more differently colored transparent layers, wherein the color filter substrate includes a frame structure which surrounds each of the differently colored transparent layers, and the differently colored transparent layers are arranged such that an average of color difference values for pairs of adjacent differently colored transparent layers becomes minimum.
