Abstract:
An auxiliary capacitor line driving circuit (5), provided in a surrounding region located around a display region (R1) in a liquid crystal display panel, generates auxiliary capacitor driving signals, and includes: first and second voltage trunk lines (VCS1, VCS2) which carry two different voltages, respectively; at least one control signal line (VCTRL1, VCTRL2) carrying one control signal; and a plurality of TFTs (T1, T2, T3, T4) each alternately supplying, to the respective auxiliary capacitor lines (CSn, CSn+1, and the like) in a given cycle, the two different voltages supplied to the auxiliary capacitor line driving circuit (5). Therefore, a liquid crystal display device employing multi-picture element drive method can be provided as a liquid crystal display device that achieves narrowing of a picture frame region as a non-display region and an external circuit board.
