Abstract: According to one embodiment, a display device includes a base, a switching element disposed above the base, a scanning line which supplies a scanning signal to the switching element, an organic insulating layer covering the switching element and having a contact hole, a pixel electrode disposed above the organic insulating layer and connected to the switching element through the contact hole, and a metal line disposed above the organic insulating layer and extending parallel to the scanning line. The scanning line, the metal line and the contact hole overlap each other in planar view.

Abstract: According to one embodiment, a liquid crystal display device includes first and second substrates and a liquid crystal layer. The first substrate includes scanning line extending in a first direction, signal line extending in a second direction, pixel electrodes including and a common electrode. The common electrode includes sub-electrodes extending in the first or second direction. Each of the sub-electrodes includes a first portion having a width greater than the scanning or signal line, and a second portion having a width less than the first portion but greater than the scanning or signal line. The first and second portions are alternately arranged along a direction in which the sub-electrodes extend.
