We have studied electro‐optic characteristics of high performance liquid crystal display using combined fringe and in‐plane horizontal electric fields, named as fringe and In‐plane switching (FIS). The strong electric fields cause more liquid crystals to reorient above and between the pixel electrodes. Moreover, the operating voltage of FIS mode was decreased by using two thin film transistors (TFTs). To suggest novel structure of FIS mode, electro optic characteristics are analyzed as a function of length between pixel electrodes compared to IPS and FFS mode. Consequently FIS mode shows not only higher transmittance but also lower operating voltage than those of IPS and FFS mode while keeping wide viewing angle.
