Patent ID: 8542228

Claim:
A liquid crystal display, having pixels aligned in a row direction and a column direction, the row direction being a direction in which scanning signal lines are extended, the liquid crystal display comprising pixel columns, first data signal lines, and second data signal lines, a first data signal line and a second data signal line being provided for each pixel column, each pixel included in the pixel column being connected with a scanning signal line, in a case where every two pixels in the pixel column are paired, one of two pixels in each pair being connected with the first data signal line and the other of the two pixels being connected with the second data signal line, two scanning signal lines respectively connected with two pixels in a pair being simultaneously selected during one horizontal scanning period so that signal potentials are written into the two pixels in a pair 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 being performed after supply of preliminary potentials to the first data signal line and the second data signal line, wherein the preliminary potential is based on a signal potential supplied to a data signal line during a previous horizontal scanning period and a signal potential to be supplied to the data signal line during a current horizontal scanning period, and the preliminary potential is represented by, Vr=Vq +{( Vq−V com)−( Vp−V com)}/2, Vr represents the preliminary potential, Vp represents a signal potential supplied to a data signal line during a previous horizontal scanning period, Vq represents a signal potential supplied to the data signal line during a current horizontal scanning period, and Vcom represents a common electrode potential.
