<P>PROBLEM TO BE SOLVED: To provide a liquid crystal display for reducing display inversion due to a voltage applied in a non-selection period for improving the bar-code reading accuracy. Ž<P>SOLUTION: The liquid crystal display includes a sensing means 3 for sensing a scanning electrode of a bar-code display portion and determines a region in the display panel 1 to display a bar-code. By determining a display state by successively applying voltage to the scanning electrodes other than one sensed by the sensing means 3, and finally applying voltage to the scanning electrodes in the bar-code portion successively or simultaneously, display quality of the bar-code is improved so as to improve the reading accuracy of the bar-code.
