A liquid crystal display panel driving device is provided which is capable of reliably improving a response speed of a liquid crystal and of obtaining good display quality. When overshooting driving is performed in a current frame for displaying, an excessive response level in a next frame is predicted based on a combination of a gray level in one past frame and a gray level in a current frame and, when an excessive response is predicted, a corrected gray-level value to prevent (or to cancel) the excessive response is calculated in advance. By applying a voltage corresponding to the corrected gray-level value, an excessive response in a next frame can be suppressed. Irrespective of whether or not an excessive response is predictable in a next frame, an overshooting driving can be performed at an applied voltage sufficiently corresponding to a target gray-level value and, as a result, a response speed of a liquid crystal can be reliably made high and good display quality can be obtained.
