Abstract:
1. A liquid crystal display device in which a liquid crystal layer is put between a TFT substrate and a counter substrate, the TFT substrate having a first electrode formed in a planar shape, a second electrode disposed above the first electrode by way of an insulative film, and a display region where pixels each formed with a TFT are arranged in a matrix, the counter substrate being disposed opposed to the TFT substrate and formed with a color filter, and the liquid crystal layer is sealed by a sealant formed at the periphery of the TFT substrate and the counter substrate, wherein an electrical field generated between the first electrode and the second electrode on the TFT substrate rotates liquid crystal molecules of the liquid crystal layer so as to control a transmittance of a light from a backlight, wherein scanning lines are extended in a first direction and arranged in a second direction, and video signal lines are extended in the second direction and arranged in the first direction in the display region, wherein scanning line leads that connect the scanning lines with a scanning line driving circuit are formed to the outside of the display region, wherein a shield electrode formed coplanar with the first electrode is extended as far as a portion below the sealant while covering the scanning line leads, and the insulative film is present between the shield electrode and the sealant, wherein a potential identical with a potential of the first electrode is applied to the shield electrode, and wherein a portion overlapped with the sealant and another portion not overlapped therewith in a planar view are present in the shield electrode, and a width L
