In a liquid crystal display, a first data signal line and a second data signal line are provided for each pixel column. In at least one embodiment, in a case where every two pixels in the pixel column are paired, one of two pixels in each pair is connected with the first data signal line and the other of the two pixels is connected with the second data signal line, two scanning signal lines respectively connected with the two pixels are simultaneously selected during one horizontal scanning period so that signal potentials are written into the two pixels from the first data signal line and the second data signal line, respectively, during each horizontal scanning period, supply of the signal potentials to the first data signal line and the second data signal line is performed after supply of preliminary potentials to the first data signal line and the second data signal line. This allows improving the display quality of a liquid crystal display in which a larger size, higher definition, or higher-speed driving etc. makes full charging of pixels difficult even when simultaneous scanning.
