Abstract
A liquid crystal panel 1 comprises a plurality of liquid crystal display areas (picto-display area A and the dot-display area C) which are controlled and driven by different driving manners (different driving voltages), an electrode section B is disposed between the plurality of liquid crystal display areas, a driving voltage for driving the electrode section B is equal to at least one of the different driving voltages for driving the plurality of different liquid crystal display areas. Therefore, it is sure to prevent an undesired movement of ionic substances from one display area to another, thus preventing mutual interference between the plurality of liquid crystal display areas thereby preventing any of he display areas from becoming darkened or nicked, thus improving the display quality of the liquid crystal panel.
