Abstract:
1. A display driving circuit that is used for a display device, the display driving circuit configured to, cause a signal electric potential written from a data signal line to a pixel electrode included in a pixel to change in direction in accordance with a polarity of the signal electric potential by supplying a retention capacitor wire signal to a retention capacitor wire with which the pixel electrode forms a capacitor, the pixel being connected with a scanning signal line and the data signal line via a transistor wherein, said display driving circuit comprises a shift register including stages arranged in a column direction and retaining circuits corresponding to respective ones of the stages, an output of each stage of the shift register is supplied for a corresponding scanning signal line, an output of each retaining circuit is supplied for corresponding retention capacitor wire, as each of m and k is a natural number, (i) a retaining circuit corresponding to mth stage of the shift register retains or passes a first retention target signal depending on outputs of mth and (m+k)th stages of the shift register, and (ii) a retaining circuit corresponding to (m+k)th stage of the shift register retains or passes a second retention target signal depending on outputs of (m+k)th and (m+k+k)th stages of the shift register, and as n is an integer not less than 2, polarities of signal electric potentials supplied for respective pixels in a pixel column invert every n pixels adjacent in the column direction.
