Abstract

PURPOSE: To prevent the occurrence of edge domain, by providing the auxiliary electrode without contacting with the electrode of the display element using liquid crystal and taking vertical the gradient of the electric power line at the electrode edge to the electrode plane.
CONSTITUTION: On the substrate 9 of two sheets opposing each other, in which at least one of them is transparent, the up and down electrodes 1, 2 transparent are provided, and the orientation film 5 making direction the orientation of the liquid crystal 10 is provided between the substrate 9 and the liquid crystal 10. In such a display element, near the part opposing to the direction of orientation of the liquid crystal 10 of the electrode edge at the side where electric power line 7 of the upper and lower electrodes 2, 1, is concentrated, the transparent auxiliary electrode 8 is provided without contacting with the upper and lower electrodes 2, 1, so that the voltage more than the threshold value voltage of the liquid crystal 10 is not exerted, then the electric power line 7 is almost vertical and the occurrence of the edge domain having black stripes based on the defective arrangement of the electrode edge is not taken place.
