摘要： A liquid crystal display unit including a plurality of subpixels (21a, 21b) in each pixel (21) provides superior gradation over a wide viewing angle, and is produced with no increase in manufacturing cost and no deterioration of desired properties (such as reduction in brightness, contrast and response). No additional manufacturing step is required since a control capacitor electrode (8c) is formed at the same time as source and drain electrodes (8a, 8b) constituting a thin-film transistor (24). By controlling the ratio of display area and the difference in applied voltage of the subpixels (21a, 21b), preferable viewing angle properties are obtained. The display properties at the boundary of subpixels are improved by controlling the gap width and the direction of boundary of the subpixels (25), thus providing a bright display.
摘要翻译：在每个像素（21）中包括多个子像素（21a，21b）的液晶显示单元在宽视角上提供优异的等级，并且不会增加制造成本并且不会降低期望的性能（例如，亮度，对比度和响应）。由于控制电容器电极（8c）与构成薄膜晶体管（24）的源极和漏极（8a，8b）同时形成，所以不需要额外的制造步骤。通过控制显示区域的比例和子像素（21a，21b）的施加电压的差异，可以获得优选的视角特性。通过控制子像素（25）的间隙宽度和边界方向来改善子像素边界处的显示特性，从而提供明亮的显示。

摘要： An improved arrangement of a liquid crystal display device is provided in which the redundancy of known but unwanted TFT (thin film transistor) defect is suppressed so that the yield per finished liquid crystal display device products can be increased without declination in the picture quality. Each pixel of the liquid crystal display device arranged at an intersection of one of scanning lines and one of signal lines is provided with two or three TFTs and also, a storage capacitor which is formed of a portion of a gate insulating layer sandwiched between its electrode and a preceding scanning line in the previous row with using no extra masking procedure. The source, drain and gate electrodes of both the first and third TFTs are coupled to the same signal line, the electrode of the same pixel and the adjacent scanning lines, respectively. The gate, source and drain electrodes of the second TFT are coupled respectively to the same scanning line to which the gate electrode of the first TFT is coupled, the electrode of the same pixel and the electrode of a succeeding pixel provided on the opposite side of the scanning line to the same pixel. The arrangement also has a scanning driver circuit capable of activating two scanning lines at the same time for sequential one-by-one scanning operation, whereby no fault in a reproduced image will be perceived in spite of the presence of a defective TFT.
