摘要： Active matrix display devices having improved opening and contrast ratios utilize light blocking lines to improve display contrast ratios yet position the light blocking lines on the same level of metallization as the gate lines to thereby limit parasitic capacitive coupling between the data lines and the pixel electrodes. The light blocking lines are also positioned on only one side of the data lines so that improvements in the display's opening ratio can also be achieved. The light blocking lines are preferably patterned so that no overlap occurs between a display's data lines and the light blocking lines. The elimination of overlap reduces the step height in the display's pixel electrodes and thereby reduces the extent of disclination of the liquid crystal molecules in the liquid crystal material extending opposite the pixel electrodes. The light blocking lines are also preferably patterned beneath the display's data lines so that parasitic capacitive coupling between the data lines and the pixel electrodes is reduced. The light blocking lines are also preferably formed with beveled edges so that the step height in the display's pixel electrodes can be reduced even further.
摘要翻译：具有改进的开口和对比度比的有源矩阵显示装置利用遮光线来改善显示对比度，同时将遮光线定位在与栅极线相同的金属化水平上，从而限制数据线和像素电极之间的寄生电容耦合。遮光线也仅位于数据线的一侧，从而也可以实现显示器开口率的改善。遮光线优选地被图案化，使得显示器的数据线和遮光线之间不会发生重叠。重叠的消除减少了显示器像素电极中的台阶高度，从而减少了与像素电极相对延伸的液晶材料中的液晶分子的旋错程度。遮光线也优选地在显示器的数据线之下图案化，使得数据线和像素电极之间的寄生电容耦合减小。阻光线也优选地形成有斜边，使得显示器的像素电极中的台阶高度能够进一步降低。

摘要： This invention provides a semiconductor device having high operation performance and high reliability. An LDD region 707 overlapping with a gate wiring is arranged in an n-channel TFT 802 forming a driving circuit, and a TFT structure highly resistant to hot carrier injection is achieved. LDD regions 717, 718, 719 and 720 not overlapping with a gate wiring are arranged in an n-channel TFT 804 forming a pixel unit. As a result, a TFT structure having a small OFF current value is achieved. In this instance, an element belonging to the Group 15 of the Periodic Table exists in a higher concentration in the LDD region 707 than in the LDD regions 717, 718, 719 and 720.

摘要： A passivation layer is formed by coating a flowable insulating material on the substrate where a thin film transistor and a storage capacitor electrode, and a pixel electrode is formed on the passivation layer. A portion of the passivation layer is etched using the pixel electrode as a mask to make a groove on the thin film transistor, and then a black matrix is formed by filling an organic black photoresist in the groove. To increase the storage capacitance, a portion of the passivation layer is removed or to form a metal pattern on the storage capacitor electrode. A flowable insulating material is used as a gate insulating layer to planarize the substrate. In the case of the etch stopper type thin film transistor, a photo definable material is used as the etch stopper layer to reduce the parasitic capacitance between the gate electrode and the drain electrode.

摘要： A liquid crystal display device includes a driving voltage supply line 115 connected to a transfer pad 116 through a contact hole 116a. The contact hole 116a is corroded under the open air in a prior art liquid crystal display device.

摘要： Disclosed is an in-plane switching active matrix type liquid crystal display with greater improvements on color shifting and contrast. The liquid crystal display comprises an in-plane switching type liquid crystal display panel having an active device substrate, an opposing substrate and a liquid crystal layer held sandwiched between the active device substrate and the opposing substrate, a first polarizer laid out on one side of the liquid crystal display panel, a second polarizer laid out on the opposite side of the liquid crystal display panel, first to third optical compensators placed in order between the liquid crystal display panel and the first polarizer, and a fourth optical compensator placed between the liquid crystal display panel and the second polarizer. As the first to fourth optical compensators are provided to compensate for retardation of the liquid crystal layer and retardation of the polarizers, black stretching does not occur even when observation is made from any viewing angle, and a reduction in contrast does not occur. Nor does color shifting occur at the time of displaying black.
