Abstract
Lattice-shaped pixel electrodes and lattice-shaped common electrodes are provided on a substrate in which switching elements of a horizontal electric-field liquid crystal display device such as a TFT are formed. Each pixel electrode is integrally formed with one electrode of the switching element such as the TFT. Each pixel electrode has a notch at an external periphery of a horizontal bar of the lattice-shaped pixel electrode. A contact hole connecting the common signal wiring and the common electrode in the substrate is provided in an area of the notch of the pixel electrode.
