摘要： Disclosed is a simplified method for manufacturing a liquid crystal display. A gate wire including a gate line, a gate pad, and a gate electrode are formed on a substrate. A gate insulating layer, a semiconductor layer, and an ohmic contact layer are sequentially deposited, and a photoresist layer is coated thereon. The photoresist layer is exposed to light through a mask and developed to form a photoresist pattern. At this time, a first portion of the photoresist pattern which is located between the source electrode and the drain electrode is thinner than a second portion which is located on the data wire, and the photoresist layer is totally removed on other parts. The thin portion is made by controlling the amount of irradiating light or by a reflow process to form a thin portion, and the amount of light is controlled by using a mask that has a slit, a small pattern smaller than the resolution of the exposure device, or a partially transparent layer. Next, the exposed portions of conductor layer are removed by wet etch or dry etch, and thereby the underlying ohmic contact layer is exposed. Then the exposed ohmic contact layer and the underlying semiconductor layer are removed by dry etching along with the first portion of the photoresist layer. The residue of the photoresist layer is removed by ashing. Source/drain electrodes are separated by removing the portion of the conductor layer at the channel and the underlying ohmic contact layer pattern. Then, the second portion of the photoresist layer is removed, and red, green, and blue color filters, a pixel electrode, a redundant gate pad, and a redundant data pad are formed.

摘要： In an array substrate, an LCD panel having the same and an LCD device having the same, the array substrate may include an insulating substrate, a switching element (e.g., a transistor such as a TFT), a main pixel portion, a coupling capacitor and a sub-pixel portion. The switching element may be formed on the insulating substrate in a pixel region defined by gate and data lines adjacent to each other. The gate and data lines may be formed on the insulating substrate. The main pixel portion is on a first (e.g., central) portion of the pixel region. The coupling capacitor is electrically connected to the switching element. The coupling capacitor is on the insulating substrate. The sub-pixel portion is electrically connected to the coupling capacitor. The sub-pixel portion is on a second (e.g., peripheral) portion of the pixel region. Therefore, an image display quality is improved.

摘要： A liquid crystal display includes a plurality of signal lines. The signal lines are parallel to each other in a display area, the distances between the signal lines vary such that the signal lines are arranged like a fan in a fan-out area, and the signal lines are connected to a driving circuit in a connection area. Each signal line includes a single-layered portion and a double-layered portion located in the fan-out area, and the length of the single-layered portion of relatively longer signal line is relatively shorter.

The amorphous silicon layer and the gate insulating layer are etched, using the patterned light shielding film and passivation film, or the patterned passivation film also having the function of the light shielding film as the mask. Here, the gate pad, the data pad and a part of the drain electrode are exposed. A pixel electrode connected to the drain electrode, is formed and indium tin oxide (ITO) pads covering the exposed gate pad and the exposed data pad, is formed by depositing an ITO film and etching thorough the photolithography, using a fourth mask.

摘要： A gate wire is formed on the insulating substrate. The gate wire has gate lines, first and second gate electrodes connected to the gate lines, and gate pads. A gate insulating layer, first and second semiconductor layers and an ohmic contact layer are sequentially formed thereon. A data wire is formed on the ohmic contact layer. The data wire has first and second data lines, data line connectors, first and second source electrodes, first and second drain electrodes, and data pads. A passivation layer is formed on the data wire, and has contact holes respectively exposing the first and the second drain electrodes, and the gate and the data pads. Pixel electrodes, and subsidiary gate and data pads are formed on the passivation layer. As described above, the data line is provided at opposite sides of the pixel area so that variation in the pixel voltage due to the parasitic capacitance between the partitioned areas with different degree of misalignment is reduced. In addition, two TFTs are provided in each pixel area so that the parasitic capacitance between the gate and the drain electrodes in two respective partitioned areas with left-biased and right-biased misalignment is kept to be constant. In this way, the pixel voltage variation between the two partitioned areas is reduced to prevent non-uniformity in the brightness.
