A liquid crystal display device includes a TFT substrate having a display region and a terminal region and formed with an organic passivation film, a counter substrate attached to the TFT substrate through a seal part, and a liquid crystal contained inside the seal part. A hole is formed at a predetermined pitch on the organic passivation film of the TFT substrate corresponding to the seal part when viewed on a plane. When the hole is viewed on a plane, a shortest distance from the hole to the hole is four micrometers or greater and 12 micrometers or less at a height of h1=0.9×h2 from a bottom face of the hole, where a depth of the hole is defined as h2.

Abstract: Prevention of air bubbles from forming when a LCD device is applied with external impact at low temperatures. A LCD device including a counter substrate facing a TFT substrate having matrix-arranged pixels each having a pixel electrode and a TFT, and a liquid crystal held between the TFT substrate and the counter substrate. An organic-material-made overcoat film is formed on the counter substrate. A transparent-conductive-film common electrode is formed on the overcoat film. On the counter substrate first columnar spacers in contact with the TFT substrate and second columnar spacers out of contact with the TFT substrate are formed. A common-electrode hole pattern is formed in an area corresponding to the first columnar spacers. The first columnar spacers are formed on the overcoat film, whereas the second columnar spacers are formed on the common electrode.
