LIQUID-CRYSTAL DISPLAY DEVICE AND METHOD FOR DRIVING SAME

摘要

Provided is a liquid-crystal display device that uses a storage-capacitance drive method and has reduced border area and power consumption. Said liquid-crystal display device uses a low-frequency refresh with an idle period after each scanning period, and a storage-capacitance line (CL1-CLm) is laid out along each gate line (GL1-GLm). In each pixel-formation unit, a storage capacitance (Ccs) is formed between the pixel electrode of said pixel-formation unit and the storage-capacitance line laid out along the gate line connected to the gate terminal of the thin-film transistor (50) of said pixel-formation unit. A display control circuit provides a first storage-capacitance signal (CSa) and a second storage-capacitance signal (CSb) to the odd- and even-numbered storage-capacitance lines, respectively. When an idle period begins, the first storage-capacitance signal (CSa) changes to a high potential from the low potential said signal exhibits during the scanning periods (T1), and the second storage-capacitance signal (CSb) changes to a low potential from the high potential said signal exhibits during the scanning periods (T1).
