PROBLEM TO BE SOLVED: To improve display quality by preventing the mutual interference between plural screens in a liquid crystal panel. SOLUTION: In a liquid crystal panel 1 in which plural liquid crystal screens (a static screen A and a dot screen C) to be controlled by different driving systems or driving voltages are arranged on a transmission plate, the blackness and a picture miss which are to be generated because impurities are concentrated in one of the screens the liquid crystal panel by the movement of inonic materials to be generated by the difference of driving voltages of the plural liquid crystal screens are prevented by providing a electrode part B at the boundary between these plural liquid crystal screens and by supplying a voltage equal to the driving voltage of one of the plural panel screens to this electrode part B to improve the display quality of the panel.
