  • Patent number: 8384857
    Abstract: A color filter substrate disposed with a spacer is provided. The color filter substrate includes a light shielding layer and a plurality of striped color filter pattern. The light shielding layer is disposed on a substrate and defines a plurality of sub pixel regions and a plurality of light shield regions. The striped color filter patterns partially cover the light shielding regions and the sub pixel regions. Each striped color filter pattern includes a protrusion portion extending to the light shielding regions, and part of the spacer is disposed above the protrusion portion.

  • Patent number: 8189150
    Abstract: A liquid crystal display panel including a first substrate, a second substrate and a liquid crystal layer is provided. The first substrate includes a plurality of first unit regions, and each of the first unit regions includes at least a pixel region. A plurality of first alignment patterns are disposed in each of the pixel regions, wherein a width of the first alignment patterns in at least one first unit region is different from a width of the first alignment patterns in other first unit regions adjacent to the at least one first unit region. The second substrate is disposed opposite to the first substrate. The liquid crystal layer is disposed between the first substrate and the second substrate.

  • Publication number: 20120044345
    Abstract: A panel assembly alignment system and an alignment method thereof. A first panel has first alignment patterns arranged at equal pitches. A second panel has second alignment patterns arranged with a pitch between the adjacent patterns being wider as positions of the second alignment patterns are farther away from the pattern. A third panel has third alignment patterns and arranged with a pitch between adjacent patterns being narrower as positions of the third alignment patterns are farther away from the pattern. An operation unit controls a photographing unit to photograph each panel, so as to analyze an overlap portion between the first and the second alignment patterns, determine an offset direction of the second panel corresponding to the first panel, so that when the third panel is placed, the third alignment pattern conforming to the offset direction and a level of the overlap portion is overlapped with the overlap portion.

  • Patent number: 7544581
    Abstract: A method for manufacturing a display substrate is disclosed, which includes the following steps: providing a substrate; forming a plurality of bumps on an active area of the substrate and at least one marking pattern on a non-active area of the substrate; and staining the marking pattern or filling a material having low transmittance ratio into the marking pattern. The present invention further discloses a method for making a display substrate, including the steps: providing a substrate; forming a shadow layer on a non-active area of the substrate; forming a plurality of bumps on an active area of the substrate and at least one marking pattern on the shadow layer of the non-active area on the substrate; and removing a part of the shadow layer not covered by the marking pattern.

  • Publication number: 20090033841
    Abstract: A manufacturing method of a color filter substrate is provided. In the method, a substrate is provided. A first color layer, a second color layer, and a third color layer are then sequentially formed on the substrate. At least any two of the first color layer, the second color layer, and the third color layer are partially overlapped to form a number of supporters. Next, a common electrode layer is formed on the substrate to cover the first color layer, the second color layer, the third color layer, and the supporters. A light-shielding layer is then formed on the common electrode layer, and a portion of the light-shielding layer is disposed over the supporters. Based on the manufacturing method of the color filter substrate, fewer masks are required.
