  • Patent number: 8755014
    Abstract: A thin film transistor array panel for a liquid crystal display, a liquid crystal display and a manufacturing method thereof are provided. The display panel includes: a substrate; and a first electrode portion disposed on the substrate, the first electrode portion having two pairs of main edges facing each other and a first cutout oblique to the main edges, wherein the main edges include first and second edges, the first electrode portion has an oblique edge substantially parallel to the first cutout, the oblique connecting the first edge and the second edge, the first edge includes a first portion extending from the oblique edge to an end of the first cutout, and the oblique edge is substantially equal to or longer than a half of the first portion of the first edge.

  • Patent number: 7709304
    Abstract: A passivation layer is deposited and a photoresist is formed. The photoresist includes first to third portions with decreased thickness, the second portions located on portions of drain electrodes and data lines and the third portions located on portions of gate lines. A mask for forming the photoresist has rectilinear slits with width and distance of about 0.8-2.0 microns on an area corresponding to the second portions. The passivation layer and an underlying semiconductor layer as well as the photoresist are etched to expose portions of the gate insulating layer under the third portions of the photoresist as well as portions of the passivation layer under the second portions of the photoresist. The exposed portions of the passivation layer and the gate insulating layer are removed to expose the drain electrodes, the gate lines and the data lines as well as portions of the semiconductor layer, which are subsequently removed.

  • Patent number: 7595207
    Abstract: To improve product yield, light is scanned on a layer on a substrate through a mask. A pattern is formed on the substrate by the exposure of the layer. The direction of scanning is substantially perpendicular to a longitudinal direction of the pattern. The capacitance difference due to coupling of the pattern to be formed and a conductive layer formed through an insulation layer is reduced. Thus, failures of a display device are reduced and the product yield is increased.

  • Patent number: 6864935
    Abstract: A liquid crystal display includes a pixel electrode, a common electrode facing the pixel electrode, and a thin film transistor including a gate electrode connected to a gate line, a source electrode connected to a data line, and a drain electrode connected to the pixel electrode. First and second domain defining members defining domains are provided at the liquid crystal display and the drain electrode is disposed near a corner of one of the domains. The drain electrode has an edge extending perpendicular to major edges of the domains and located closest to a center of the one of the domains.
