摘　　要：提出在像素电极下方放置凸起物,获得具有宽视角特性的多畴扭曲向列相液晶显示器。该模式比传统的多畴TN模式摩擦过程少,工艺过程简单。在这种液晶显示器中,初始状态(未加电)时,分子排列结构和普通单畴TN模式相同,在加电压状态时,由于凸起物的存在,液晶分子沿着4个不同的方向排列形成多畴区域。文中运用专业液晶模拟软件模拟,对该液晶显示器的电光特性进行研究,结果表明,该液晶显示器具有宽视角、色散小及色彩还原性较好的特性。This paper proposed a wide viewing angle twisted nematic（TN） liquid crystal display（LCD） with a protrusion structure under the pixel electrode.The proposed LCD mode avoids the complex rubbing processes because of the protrusion which induces the multi-domain structure like the conventional multi-domain TN mode.As no voltage applied,the LC profile is the same as that of the normal TN cell,the LC molecules tilted four different directions to obtain the multi-domain structure while the operate voltage is applied.In this paper,the electro-optic characteristics is simulated using the professional software,and the results show that the proposed multi-domain TN LCD has the wide viewing characteristics and low color shift.
