Abstract

The present invention provides a liquid crystal display device. The liquid crystal display device (100A) is equipped with an active matrix substrate (120) having pixel electrodes (122), gate wires (G), and source wires (S), a counter substrate (140) having counter electrodes (142), and a liquid crystal layer (160). The active matrix substrate (120) additionally has a conductive layer (130) provided inside an insulation layer (134) that is between the gate wires (G) and the pixel electrodes (122). The conductive layer (130) has regions (130r) positioned between a first region (122a) and a second region (122b) of the pixel electrodes (122). The conductive layer (130) is electrically connected to the pixel electrodes (122) or the source wires (S).

Description

technical field [0001] The present invention relates to a liquid crystal display device. Background technique [0002] Liquid crystal display devices are used not only as large televisions but also as small display devices such as display units of mobile phones. Since the TN (Twisted Nematic: Twisted Nematic) mode liquid crystal display device frequently used in the past has a relatively narrow viewing angle, in recent years, IPS (In-Plane-Switching: In-Plane Switching) mode and VA (Vertical Alignment: Vertical Alignment: Vertical Alignment) mode are being produced. A liquid crystal display device with a wide viewing angle such as orientation) mode. In such a mode with a wide viewing angle, the VA mode is adopted in many liquid crystal display devices because it can achieve high contrast. [0003] As one of the VA modes, an MVA (Mutli-domain Vertical Alignment: multi-domain vertical alignment) mode in which a plurality of liquid crystal domains are formed in one pixel area...
