  • Publication number: 20070070027
    Abstract: An array substrate includes a base substrate, a plurality of storage voltage lines, a plurality of connecting lines, and a common voltage applying section. Pixels are formed in regions defined by a plurality of gate lines extending along a first direction and data lines extending along a second direction. The connecting lines are connected to the storage voltage lines that are formed on adjacent pixels of pixels arranged in the second direction. The common voltage applying section applies a common voltage to the storage voltage lines that are formed in a portion of the pixels arranged in the first direction. Thus, a substantially uniform current may be applied to the display area to decrease the distortion of the common voltage, thereby increasing a liquid crystal display device's display quality.

  • Publication number: 20070026586
    Abstract: A mask for forming a display substrate capable of improving color reproducibility by avoiding color spots and color shifts is presented. The mask includes a first sub-mask, a second sub-mask, a first overlapping portion and a second overlapping portion. The first sub-mask includes color reticles to form color pixels in a first active region of a display substrate. The second sub-mask includes color reticles to form color pixels in a second active region of the display substrate. The first overlapping portion is on a portion of the first sub-mask that overlaps the second sub-mask. The color reticles in the first overlapping portion are arranged at a different density from the rest of the first sub-mask. The second overlapping portion is on a portion of the second sub-mask that overlaps the first sub-mask. The color reticles in the second overlapping portion are arranged at a substantially same density as the first overlapping portion. Therefore, image display quality is improved.
