— A novel electrode structure which can provide a high aperture ratio in a super in‐plane‐switching (S‐IPS) liquid‐crystal (LC) cell at high transmittance is proposed. To improve the aperture ratio of the S‐IPS cell, a zig‐zag electrode pattern was applied to the electrode edge in the active area that can effectively reduce the disclination area. In addition, a novel electrode structure was also applied to the bulk area which can reduce the cross‐talk and light leakage between the pixel lines and the data lines. As a result, it was found that the proposed electrode structure could provide a higher aperture ratio than that of the conventional type by reducing the black matrix (BM) area so that a high transmittance compared to that of the conventional structure can be achieved.
