Abstract
A liquid crystal display device is configured to prevent the appearance on its display of a black stain stemming from a drop in volume resistivity of liquid crystal caused by ions therein. The device includes a thin-film transistor (TFT) substrate and a counter substrate bonded together along the periphery thereof by a seal material. The TFT substrate and the counter substrate have liquid crystal sandwiched therebetween and include a display region. A third electrode is formed outside the display region of the TFT substrate. A concave portion is formed in an organic insulation film on the liquid crystal side of the third electrode.
