Title:
ACTIVE MATRIX SUBSTRATE AND LIQUID CRYSTAL DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2012/137472
Kind Code:
A1
Abstract:
In n+1 data lines (D) of an active matrix substrate of the present invention, data lines to which an anodic data signal is applied and data lines to which a cathodic data signal is applied are arranged alternately in the row direction. Pixel sections (P1k - Pmk) each include: a liquid crystal element (21); a first switching element (22) that switches the connection state of the liquid crystal element (21) and the data line (D(k)) of the kth column in response to a control signal that is applied to one of first and second gate lines (Ga(j), Gb(j)); and a second switching element (23) that switches the connection state of the liquid crystal element (21) and the data line (D(k+1)) of the (k+1)th column in response to a control signal that is applied to the other of the first and second gate lines (Ga(j), Gb(j)). According to the present invention, power consumption can be reduced because dot inversion drive can be performed without inverting the polarity of the data signal that is applied to each of the data lines in each single frame. The present invention is applicable to liquid crystal display devices.
