Abstract
A liquid crystal display device of the present invention capable of enlarging and displaying to a high picture quality even when display data having a lower resolution than a liquid crystal panel is inputted, is provided with storage element groups every drain line within latches of a liquid crystal driver. A portion of the storage element groups simultaneously captures display data. In doing so, the same liquid crystal apply voltage is outputted from drain lines corresponding to these storage element groups. Storage element groups corresponding to neighboring drain lines then simultaneously capture display data so as to enlarge an image in the horizontal direction. The rate of enlargement can be regulated by changing the number of storage element groups simultaneously capturing display data. A scanning driver then simultaneously selects a plurality of rows with a select voltage being applied to the simultaneously selected rows of pixel elements in the same period so as to enlarge the image in the vertical direction. Enlarged displaying is therefore possible by the liquid crystal driver regulating an output period of the liquid crystal apply voltage even when rows are selected one at a time.
