  • Patent number: 8778576
    Abstract: In an exposure method, a photomask and a substrate having a resist applied thereto are positioned so as to be opposed to a blinking light source that repeatedly emits light and emits no light. The blinking light source is caused to blink with the substrate being continuously conveyed in a direction orthogonal to a direction in which openings in the photomask are aligned, so that multiple exposures are intermittently performed. In each exposure, a speed at which the substrate is conveyed is controlled such that the openings of the photomask overlap a portion of exposed patterns having been obtained by an immediately preceding exposure, thereby obtaining colored layers which are formed into a striped-shape and extend in the direction in which the substrate is conveyed.

  • Patent number: 8749734
    Abstract: Unevenness due to the influence of a mesh when a sealing material for bonding a TFT substrate and a counter substrate together is formed on the counter substrate by screen printing is prevented. Light shielding films are extended in the horizontal direction and arranged in the vertical direction. Red color filters, blue color filters, and green color filters are extended in the vertical direction at predetermined intervals. The blue color filters are extended also in the horizontal direction so as to cover the light shielding films. In a cross section along the red color filter and the green color filter, the level of a portion above the light shielding film is higher compared with that of the other portion by the thicknesses of the blue color filter and the light shielding film. In screen printing, since the high portion serves as a stopper for the mesh, the occurrence of unevenness due to the mesh can be prevented.
