Abstract

There is provided a liquid crystal display device that enables increasing the capacitance between a pixel electrode and a common electrode without bringing about a significant decrease in the pixel aperture ratio. An In-Plane Switching LCD device in which a drain signal is supplied from one drain signal line to two pixel columns is configured such that there is a section having no drain signal line between adjacent pixels and a source electrode which is connected to a pixel electrode of a thin-film transistor extends into a contiguous pixel region that does not serve as an effective pixel region to provide one electrode of a capacitive element. A common electrode is formed in each pixel and the one electrode of the capacitive element is laid overlapping the common electrode with an insulation film intervening therebetween.
