发明名称 LIQUID CRYSTAL DISPLAY DEVICE
摘要 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.
