Abstract

Abstract Translated from Japanese (57)【要約】 【目的】 垂直配向マトリクス液晶表示装置において、 液晶分子の配向方向を制御することにより、ディスクリ ネーションの出現による、表示品位の低下を防止すると ともに、視角特性を向上する。 【構成】 画素間に配向制御電極(4)を設け、これに 他の全ての透明電極よりも高いか、または、低い実効電 圧を印加し、かつ、透明電極に電極不在により形成され た配向制御窓(5)を設けることにより、液晶層(3) 中の電界を調整して、液晶分子の配向を制御する。 (57) [Abstract] [Purpose] In a vertical alignment matrix liquid crystal display device, By controlling the alignment direction of the liquid crystal molecules, it is possible to prevent the display quality from deteriorating due to the appearance of disclination and to improve the viewing angle characteristics. [Arrangement] An alignment control electrode (4) is provided between pixels, an effective voltage higher or lower than that of all other transparent electrodes is applied to the alignment control electrode (4), and the alignment control is formed by the absence of electrodes on the transparent electrode. By providing the window (5), the liquid crystal layer (3) The alignment of the liquid crystal molecules is controlled by adjusting the electric field inside.
