摘要： A display device which has a liquid crystal display which has a plurality liquid crystal pixels arranged in a matrix and which writes an image thereon after resetting the liquid crystal. The method of writing on the liquid crystal display can be selected from driving methods according to interlace scanning in which a frame is divided into a plurality of fields and writing by interlace scanning is performed and driving methods according to sequential scanning in which scanning lines are subjected to writing serially. When high-speed writing is required, for example, when display of a motion picture, display of inputted letters or scroll display is desired, one of the driving methods according to interlace scanning is selected. In interlace scanning, based on the end of a blackout state of a scanning line in a field, selection of a scanning line in the next field for writing is started. Writing on a scanning line comprises a reset step of resetting the liquid crystal, a selection step of selecting the final state of the liquid crystal, an evolution step of stabling the liquid crystal into the selected state, and one of the length of the reset step and the total length of the selection step and the evolution step is n times (n: natural number) the other. For example, when the length of the reset step is n times the total length of the selection step and the evolution step and when a frame is divided into m fields (m: natural number larger than n) for interlace scanning, there is a moment when, in serial m scanning lines, n scanning lines of them are in the reset step, one of them is in the selection step or in the evolution step, and the other m-n-l scanning lines are in a display step.
