Abstract:
The present application discloses an active matrix type display device that is capable of successfully displaying an image by an intra-screen division drive while suppressing the complication of a circuit configuration. In a liquid crystal panel that includes an A area and a B area, an A area scanning signal line and a B area scanning signal line are scanned in the same direction, and the A area data signal line and the B area data signal line are driven based on an A area image signal DaA and a B area image signal DaB, respectively, that are obtained from an image signal DA from the outside. Furthermore, when a scanning signal line that is to be selected latest in the A area is selected, a voltage that is the same as a data signal voltage which is applied to the A area data signal line that intersects the scanning signal line is applied to the B area data signal line that is paired with the A area data signal line. Moreover, for the purpose of suitable preliminary charging with an intra-screen division drive, a voltage for the preliminary charging is applied to a data signal line in each of the A area and the B area, immediately before a data signal is applied to a head data signal line in each of the A area and the B area.
