    • A liquid crystal display device of the invention can, when a liquid crystal panel receives a pressing force from the outside, prevent the displacement of columnar spacers which are formed over a counter substrate for defining a distance between the counter substrate and a TFT substrate in the direction parallel to the substrate. In a case where the TFT substrate or the counter substrate receives a pressing force from the outside, when the columnar spacers which define the distance between the TFT substrate and the counter substrate are displaced in one or more directions, the alignment disorder of liquid crystal molecules occurs or an alignment film is shaved so that leaking of light occurs due to shaved chips of the alignment film and hence, contrast of an image is lowered. Projections are formed on a TFT substrate side by making use of bus electrodes provided for preventing lowering of a voltage of counter electrodes. When the TFT substrate or the counter substrate receives a pressing force from the outside, the projections bite into a distal end of the columnar spacer so that the displacement of the columnar spacer in one or more directions can be prevented.
    • 本发明的液晶显示装置,当液晶面板受到来自外部的按压力时,可以防止在对置基板上形成的柱状间隔物的位移,用于限定对置基板与TFT基板之间的距离 方向平行于基板。 在TFT基板或对置基板受到来自外部的按压力的情况下,当限定TFT基板和对置基板之间的距离的柱状间隔件在一个或多个方向上位移时,液晶分子的取向障碍 发生或定向膜被刮削,使得由于对准膜的切屑而发生光的泄漏,因此图像的对比度降低。 通过利用设置用于防止对置电极的电压降低的总线电极,在TFT基板侧上形成投影。 当TFT基板或对置基板受到来自外部的按压力时,突起咬入柱状间隔件的远端,从而可以防止柱状间隔件在一个或多个方向上的位移。
