摘要： A display substrate includes source lines, gate lines, an output pad part, a fan-out part and a first voltage line part. The source lines are in a display area. The gate lines cross the source lines. The output pad part is in a peripheral area surrounding the display area and is electrically connected to output terminals of a driving chip. The fan-out part is electrically connected between the output pad part and the source lines. The first voltage line part is inclined with respect to a central line of a chip area in which the driving chip is mounted toward opposite sides of the chip area to cross the fan-out part. Therefore, the line reactance of the fan-out part is decreased and the uniformity of the line resistance of the fan-out part is increased to improve image display quality.

摘要： The present invention relates to an LCD that has a first panel, a second panel, a sealant, and a liquid crystal layer between the two panels. The first panel includes a pad provided in a first part of a non-display region and a dummy metal pattern provided in a second part of the non-display region along a circumference of a display region. The second panel is positioned opposite the first panel so that the two panels sandwich the liquid crystal layer. A sealant is formed on the pad and the dummy metal pattern and couples the first panel with the second panel. Thus, an LCD described herein has a uniform cell gap. A method of fabricating an LCD that has a uniform cell gap is also disclosed.

摘要： A gate wire including a gate line extending in the horizontal direction, and a gate electrode is formed on an insulating substrate. A gate insulating layer is formed on the gate wire and covers the same. A semiconductor pattern is formed on the gate insulating layer 30, and formed on the semiconductor pattern are a data wire having a date line in the vertical direction, a source electrode, a drain electrode separated from the source electrode opposite the source electrode with respect to the gate electrode, and an align pattern located on both sides of the data line. A passivation layer is formed on the data wire and the align pattern, and has contact holes exposing the drain electrode and an opening exposing the substrate between the data line and the align pattern. Here, the align pattern adjacent to the data line is exposed through the opening, and the semiconductor pattern and the gate insulating layer are under-cut. A pixel electrode connected to the drain electrode through the contact hole is formed on the passivation layer. Here, the opening is located between the data line and the pixel electrode. In this structure, misalignment occurring in the manufacturing process of a thin film transistor panel for a liquid crystal display is minimized, and stitch defects are prevented by uniformity forming a coupling capacitance between the data line and the pixel electrode. Shorts between the data line and the pixel electrode are prevented by forming the opening between the data line and the pixel electrode.

摘要： A gate driver circuit includes a driving section and a wiring section. The wiring section receives a plurality of signals from an external device. The driving section includes a plurality of stages providing a plurality of gate lines with a gate signal. The wiring section includes first and second signal wirings. The first signal wiring is disposed adjacent to a first side of the driving section, where the first side receives the signals from the wiring section. The second signal wiring is disposed adjacent to a portion that is disposed at an outer side of the driving section and the first signal wiring. Therefore, a signal applied to the first signal wiring is prevented from being delayed by the second signal wiring. Furthermore, a distortion of signal applied to the gate driver and a maloperation of the gate driver are prevented.

摘要： A plurality of gate lines formed on an insulating substrate, each gate line including a pad for connection to an external device; a plurality of data lines intersecting the gate lines and insulated from the gate lines, each data line including a pad for connection to an external device; and a conductor overlapping at least one of the gate lines and the data lines are included. An overlapping distance of the gate lines or the data lines and a width of the conductor decreases as the length of the gate lines or the data lines increases. Accordingly, the difference in the RC delays due to the difference of the length of the signal lines is compensated to be reduced.

摘要： A liquid crystal display having electrodes on a single substrate. A transparent planar electrode elongated in the transverse direction is formed on the inner surface of a substrate, and an insulating film is deposited thereon. A plurality of linear electrodes, which are elongated in the longitudinal direction and either transparent or opaque, are formed on the insulating film. Potential difference between the planar and the linear electrodes generated by applying voltages to the electrodes yields an electric field. The electric field is symmetrical with respect to the longitudinal central line of the linear electrodes, and has parabolic or semi-elliptical lines of force having a center on a boundary line between the planar and the linear electrodes. The line of force on the planar and the linear electrodes and on the boundary line between the planar and the linear electrodes has the vertical and the horizontal components, and the liquid crystal molecules are re-arranged to have a twist angle and a tilt angle. The polarization of the incident light varies due to the rearrangement of the liquid crystal molecules.
