<p>PURPOSE:To easily control color density by dividing a nondriving electrode into plural small electrodes in each unit picture element, and giving a potential difference to the small electrodes and making variation in transmission quantity variation characteristics slow. CONSTITUTION:The nondriving electrode 6 is divided into the small electrodes 61a, 61b, and 61c in each unit picture element and put opposite a driving electrodes 11 equipped with a thin film transistor (TR) TFT12 across a liquid crystal layer 2, and voltages Va, Vb, and Vc are applied to those small electrodes 61a, 61b, and 61c. Here, when a data voltage exceeds a threshold value V1, the quantity of transmission of the liquid crystal layer sandwiched between the electrode 61a and electrode 11 varies at the threshold value V1 as well as a conventional liquid crystal panel and becomes minimum at a voltage V2, obtaining a curve I. Similarly, the quantity of transmission in the case of the electrode 61b begins to vary above a threshold value V2 and becomes minimum at a voltage V3, obtaining a curve II. Further, the quantity in the case of the electrode 61c begins to vary at a threshold value V3 and becomes minimum at a voltage V4, obtaining a curve III. Then, their total characteristic curve V has a slower gradient than the conventional curve I where Va=Vb=Vc=0.</p> |
