摘要： A liquid crystal display has a gate line structure for serving as a storage electrode and a black matrix and performing a repair function. In the liquid crystal display, a gate dummy pattern is formed in such a manner to be extended in the vertical direction from the gate line and to overlap with the data line and the pixel electrode. The gate dummy pattern branches from the gate line, overlaps the edge of a pixel, serves a storage electrode and a black matrix, and permits repair upon breakage of a data line.

摘要： An LCD panel includes a plurality of gate lines and gate electrodes formed on a substrate and a gate insulating film formed on the substrate including the gate lines and the gate electrodes. A semiconductor film is formed in a region on the gate insulating film and an ohmic contact film formed on the semiconductor film. A plurality of data lines cross the gate lines; a source electrode is formed on the ohmic contact film; and a pixel electrode is formed in a pixel region defined by the gate and data lines. A drain electrode is formed on the ohmic contact film, and has an uneven width. Since a portion of drain electrode that overlaps with the gate electrode has a smaller width than a width of other portions of the drain electrode, variation in an area of the drain electrode overlapped with the gate electrode is small, so that variation of the parasitic capacitance can be reduced, thereby improving picture quality.

摘要翻译： LCD面板包括形成在基板上的多个栅极线和栅电极以及形成在包括栅极线和栅电极的基板上的栅极绝缘膜。半导体膜形成在栅绝缘膜上的区域和形成在半导体膜上的欧姆接触膜。多条数据线与栅极线交叉; 源电极形成在欧姆接触膜上; 并且像素电极形成在由栅极和数据线限定的像素区域中。在欧姆接触膜上形成漏电极，其宽度不均匀。由于与栅电极重叠的漏电极的一部分的宽度小于漏电极的其他部分的宽度，所以与栅电极重叠的漏电极的面积的变化小，使得寄生电容的变化可以减少，从而提高图像质量。

摘要： A thin film transistor array substrate for a liquid crystal display panel includes a gate line formed on a substrate. A data line crosses the gate line, thus defining a pixel region. A gate insulating film is positioned between the data line and the gate line. A thin film transistor is formed at a crossing of the gate line and the data line. A passivation film pattern exposes a portion of a drain electrode of the thin film transistor. At least one protrusion is provided to divide the pixel region into a plurality of regions, each of the regions having a different liquid crystal alignment from the other regions. A pixel electrode is connected to the thin film transistor to cover the pixel region excluding the passivation film pattern and the at least one protrusion.

摘要： Disclosed is a thin film transistor substrate for a fringe filed switching type liquid crystal display device, and a fabrication method thereof, that reduces the number of required mask processes, and thus improves fabrication efficiency. The fabrication method involves three mask processes, wherein the masks are partial transmitting masks, and the resulting photo-resist patterns have varying thicknesses. By having photo-resist layers of varying thicknesses, structures can be formed in multiple etching steps using the same photo-resist pattern by incrementally removing the photo-resist according to its thickness. The thin film transistor substrate has a common line, a common electrode, a gate line and a gate electrode formed directly on the substrate. The common electrode overlaps the pixel electrode in the pixel area.
