<p>At the time of displaying a still image, a control section (6) outputs an inputted image data signal (DAT) to a source driving section as it is and performs display driving. At the time of displaying a moving image, the control section (6) converts a tone level signal of the inputted image data signal (DAT) into a tone level signal not using an applying voltage which makes a response speed of liquid crystal within a late range by using an operating section (61) and a lookup table (5), and performs display driving by outputting the converted tone level signal to the source driving section.</p>
