    • It is to make the sizes of “blur” in a moving image uniform in a liquid crystal display unit of a hold-type display device by suppressing deformations and discolorations of the moving image caused due to ununiformity in the response speed of the liquid crystal panel. The display device includes a frame memory and a correction frame signal generating device as correction frame signal generating devices which compare pixel gradation levels defined by one frame and a frame one before among the image signals inputted from the outside, and generate an image signal of a correction frame for reducing a delay in the response time of the pixel. At the same time, the liquid crystal display device displays the correction frame on the liquid crystal panel between that one frame and the frame one before.

    • 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.
