Abstract
In a liquid crystal display device, in each unit pixel which is formed as a region surrounded by scanning signal lines and data signal lines, that is a pixel electrode to which signals of the data signal line are electrically supplied through a thin film transistor, and a common electrode is provided, which is electrically connected with a common signal line. The common electrode is arranged so as to be superposed on the common signal line by way of an insulation layer. The pixel electrode is electrically connected with a source electrode of the thin film transistor via a through hole which penetrates the insulation layer, and the common electrode is formed so as to extend in the inside of the unit pixel, while covering the common signal line.
