  • Patent number: 7453545
    Abstract: In a liquid crystal display panel, by controlling the number or a size of a support member added to a seal pattern for attaching two substrate of a liquid crystal display panel to each other, in case that the seal pattern is formed at an upper surface of a black matrix or of an over-coast layer formed of an organic film material, outer air is prevented from flowing into an image display part, and the seal pattern is prevented from being broken, so that it may be minimized that a deficiency occurs in the liquid crystal display panel.

  • Publication number: 20050256695
    Abstract: A method, system, and computer-readable medium for creating visual data models from multiple inter-related model segments is described. In order to create inter-relationships between model elements in different model segments, a model segment can include one or more external model elements. Each external model element in a model segment is a reference to another actual model element whose definition or description is located outside the model segment (e.g., in another model segment). After an external model element is created in a model segment, a variety of relationships can be defined between the external model element and other model elements in the model segment. Such a relationship with an external model element signifies a relationship with the actual model element represented by the external model element.
