  • Patent number: 7924276
    Abstract: 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.
