Abstract

See full text

Provided is a liquid crystal display device with a touch sensor in which abnormal alignment of liquid crystal molecules of a liquid crystal layer is hardly generated even when charged bodies get closer to the liquid crystal display device. The liquid crystal display device with a touch sensor includes a liquid crystal layer 13 interposed between a CF substrate 11 (a first substrate) and an array substrate 12 (a second substrate), in which at least one electrode of touch drive electrodes 14 and touch detection electrodes 15 is disposed on a surface of a front side of the CF substrate 11 and a polarizing plate 17 is further disposed on the electrode. On the surface of the front side of the CF substrate 11, dummy electrodes 16 are disposed in a region where neither the touch drive electrodes 14 nor the touch detection electrodes 15 are arranged. The polarizing plate 17 includes a conductive layer having a surface resistance of 109 (Ω/□) or more and 1010 (Ω/□) or less.
