shown in fig1 b a reference voltage such as a ground voltage is applied to each of the third electrodes 18 and the fourth electrodes 20 through the third connection electrode 18 a and the fourth connection electrode 18 a respectively accordingly the third electrodes 18 and the fourth electrodes 20 are operated like a single body electrode accordingly during the first period t 1 in the second mode m 2 the first electrodes 14 and the second electrodes 16 operate the liquid crystals and the third electrodes 18 and the fourth electrodes 20 formed on the second substrate 12 serve as a common electrode when the barrier 200 is a liquid crystal display using a normally black mode of transmission portions of the barrier on which the first electrodes 14 are located serve as light transmission portions and portions of the barrier on which the second electrodes 16 are located serve as light interception portions during the first period t 1 when the barrier 200 is a liquid crystal display using a normally white mode of transmission portions of the barrier on which the first electrodes 14 are located serve as light interception portions and portions of the barrier on which the second electrodes 16 are located serve as light transmission portions during the first period t 1 accordingly the barrier 200 features a striped pattern such that the light transmission portions of the barrier are formed to extend along the second direction the direction of the y axis in fig1 a and 12b in the third period t 3 during which the panel.
