摘要： While securing adequate response characteristics and brightness of an orientation-divided vertical alignment type liquid crystal display device, variations in display quality that are ascribable to variations in the pixel structure are suppressed. A liquid crystal display device according to the present invention includes a plurality of pixels each having a first electrode, a second electrode opposing the first electrode, and a vertical-alignment type liquid crystal layer provided between the first electrode and the second electrode, including: a rib provided on the first electrode side of the liquid crystal layer, and a slit provided in the second electrode of the liquid crystal layer. The thickness of the liquid crystal layer is no more than 2.5 μm, and the width of the rib is no less than 5 μm and no more than 13 μm.

摘要： A liquid crystal panel (2) includes scanning signal lines (31) for supplying scanning signals to gate electrodes (20) of TFTs (14), and data signal lines (32) for supplying data signals to data electrodes (24) of TFTs. The liquid crystal panel further includes auxiliary capacitive electrode pads (27a) for use in forming auxiliary capacitance and an auxiliary capacitive lines (33) so as not to generate a capacitive bond with the scanning signal lines. The liquid crystal panel is driven at a rewriting frequency of a screen of not more than 30 Hz. As a result, the liquid crystal panel can be driven at a low consumption power while maintaining a desirable display quality of the liquid crystal panel.

摘要： A liquid crystal display apparatus has an improved repair success rate. In the liquid crystal display apparatus, a pixel electrode is electrically connected to a drain electrode of a thin-film transistor. The drain electrode has a substantial correction site which is narrowed in width. An opening is formed in a certain region of said pixel electrode, overlying the substantial correction site of the drain electrode, the opening being in contact with the outer periphery of the pixel electrode.
