ABSTRACT:
An LCD device comprising an LCD for changing the size of a displayed unit of pixels by electrically connecting a plurality of display electrodes in parallel with one another for time-sharing matrix driving liquid crystal pixels arranged as a matrix wherein image data is independently inputted into upper and lower half portions of the LCD, a display controller for outputting upper and lower side image data to be displayed on the upper and lower half portions of the LCD and synchronous signals. The LCD device further comprises an upper side image data-holding memory and a lower side image data-holding memory for dividing image data in a given display area from a screenful of image data outputted from the display controller into new upper and lower side image data to be written and held in the upper and lower side image data-holding memories. The upper and lower side image data held in the upper and lower side memories are read out to be repeatedly displayed on the upper and lower half portions of the LCD. As a result, the image from any desired display area of a full-screen area can be enlargedly displayed on a full-screen area of a display with high quality and be easily visible without being discontinuous.
