<p>Data signal lines (S1 to Sm) are driven by a first data signal line drive circuit (11) provided along one side in the row direction of a pixel array (1) and a second data signal line drive circuit (12) provided along the other side in the row direction of the pixel array (1). The first data signal line drive circuit (11) includes switches (15) for selecting whether or not to apply video signals (V1, V2) to the data signal lines (S1, S2) and so forth and flip-flops (13) for controlling the switches (15). The second data signal line drive circuit (12) includes flip-flops (14) having a similar function and switches (16). The switches (15, 16) are so controlled that the conducting periods of the switches (15, 16) supplied with the same video signal do not overlap with one another and at least part of the conducting periods of the switches corresponding to adjacent data signal lines overlap with one another. With this, a liquid crystal display in which no vertical line nor ghost appears on the screen and which has a narrow frame can be provided.</p> |
