A liquid crystal display device includes a substrate having a display region and a non-display region. In the display region, the gate line and a data line cross to define a pixel region and a thin film transistor is disposed at the crossing portion of the gate and data lines. The thin film transistor includes a gate electrode and source and drain electrodes. A peripheral line having a plurality of openings is disposed in the non-display region. The openings are slits, rectangles, circles, or triangles. The openings relieve plasma during dry-etching of the peripheral line. A pixel electrode is connected to the drain electrode in the pixel region.

Liquid crystal display device and method for removing residual charge

In order to prevent exposure mismatch on a boundary between exposure regions that causes pattern connection defects (including stitch defects), exposure is performed twice or more on a whole exposure region of a glass substrate. The exposure method includes aligning a reticle in a scanning direction, exposing the reticle pattern onto the glass substrate, moving the glass substrate one-half of the width of the reticle, and exposing an exposure area twice by repeating the exposing and moving steps.

Liquid crystal display substrate fabrication

The present invention provides an array substrate for an IPS-LCD device. The array substrate has an image display area and an image non-display area. A plurality of pixels are disposed in the display area. A plurality of switching devices each of that is disposed in each pixel are on the substrate. First and second lines apply signals to each switching device, and a plurality of first electrodes on the substrate are connected to each switching device. A plurality of second electrodes on the substrate are spaced apart from each first electrode. A plurality of electrostatic discharge devices are arranged in the non-display area, and each electrostatic discharge device is at a distance of more than one pixel pitch. A plurality of pads are arranged in the non-display area. A plurality of first connecting lines each of that connects each pixel to each electrostatic discharge device are arranged in the non-display area. A plurality of second connecting lines connect the electrostatic discharge devices to the pads.
