    Abstract: According to an aspect, a display device with a sensor includes: a first substrate; detection electrodes arrayed in a matrix in a first direction and a second direction intersecting the first direction above the first substrate; sensor wires coupled to one of the detection electrodes; pixels each including sub-pixels and arrayed in a matrix in the first and second directions; scanning lines scanning switching elements of the sub-pixels and extending in the first direction; and signal lines coupled to the switching elements and extending in the second direction. One of the sensor wires overlaps one of the signal lines. The sensor wires each have, at a part thereof, a coupling part coupled to the corresponding detection electrode. The pixels include a first pixel with the coupling part and a second pixel without the coupling part. The first and second pixels are alternately disposed in the first and second directions.

    Abstract: According to one embodiment, a liquid crystal display device comprises first and second substrates and a liquid crystal layer between the substrates. The first substrate includes scanning lines, video lines, a sub-pixel area, a pixel electrode in the sub-pixel area, and a common electrode which generates an electric field between the pixel electrode and the common electrode. The sub-pixel area has a width of 13 μm or less. A gap d between the first substrate and the second substrate is 2.5 μm or less. A liquid crystal material contained in the liquid crystal layer has a refractive anisotropy Δn of 0.1 or more. A product Δnd of the gap d and the refractive anisotropy Δn is 0.20 μm or more and 0.31 μm or less.
