Abstract
A liquid crystal panel () is provided with a connection switching circuit () for connecting a video signal line driving circuit () to a plurality of video signal lines (Ls). The connection switching circuit () includes analog switches (SW) that correspond to the video signal lines (Ls) and one side of each of the analog switches (SW) is connected to one of the video signal lines (Ls). The video signal lines (Ls) are grouped together into groups of two video signal lines (Ls) that are spaced apart by one video signal line. The groups of video signal lines (Ls) respectively correspond to output terminals (TS) of the video signal line driving circuit (). The other sides of the analog switches (SW) connected to the video signal lines (Ls) of the same group are connected to one another, and connected to one output terminal (TS). Based on a switching control signal GS, the analog switches (SW) connect each of the output terminals (TS) in each horizontal scanning period by time division to the two video signal lines (Ls) of the corresponding group.
