Abstract

According to one embodiment, a liquid crystal display includes a display region including a plurality of display pixels arrayed in a matrix, an array substrate including a plurality of first electrodes which are arrayed in a matrix, a plurality of first sensors which extend in a column direction on the first electrodes, and a plurality of second sensors which extend in a row direction substantially perpendicular to the column direction and are electrically connected to the first sensors, a countersubstrate which is arranged to face the array substrate, and a liquid crystal layer which is interposed between the array substrate and the countersubstrate. The first sensors include omitted portions which connect adjacent regions surrounded by the first sensors and the second sensors.
