According to one embodiment, a display device includes a first drain electrode, a first insulating film which is organic, a first metal electrode in contact with the first drain electrode in a first through-hole of the first insulating film, a second insulating film which is organic, a first transparent electrode in contact with the first metal electrode in a second through-hole of the second insulating film and formed of a transparent conductive material, a third insulating film which is inorganic, a pixel electrode in contact with the first transparent electrode in a third through-hole of the third insulating film and a metal wire located between the first insulating film and the second insulating film and formed of a material identical to that of the first metal electrode.

Display device

According to one embodiment, a display device includes a switching element, a common electrode, an insulating film covering the common electrode, a first pixel electrode electrically connected to the switching element in a first contact hole penetrating the insulating film, and a transparent conductive film electrically connected to the common electrode in a second contact hole penetrating the insulating film. The first pixel electrode and the transparent conductive film are arranged in a first direction in a same layer. A size of the first contact hole and a size of the second contact hole are different from each other in planar view.

According to one embodiment, a display device includes a first substrate, a second substrate, and a connection member. The first substrate includes a pad portion. The second substrate includes a transparent conductive film located on an outer surface. The connection member electrically connects the pad portion and the transparent conductive film. The pad portion includes a second metal layer, a first organic insulating film having a first through hole penetrating to the second metal layer, a third metal layer being in contact with the second metal layer in the first through hole, and a second organic insulating film covering an end portion of the third metal layer and having a second through hole penetrating to the third metal layer.

A display portion of a display device includes a gate wiring formed of a first metal layer, a signal line formed of a second metal layer, a metal wiring formed of a third metal layer. A terminal portion of the display device includes a first metal portion formed of the second metal layer, and a second metal portion that is laminated on the first metal portion and formed of the third metal layer. The second metal portion covers an upper surface and a side surface of the first metal portion, and a peripheral portion of the second metal portion is covered by an organic insulating film, and the inside of the peripheral portion of the second metal portion is exposed via a first through hole formed in the organic insulating film.

A display device has a frame region in a displaying region. The frame region includes a first scan line, and a first signal line and a second signal line adjacent to each other. The first signal line has a first wide section, and the first signal line intersects the first scan line at the first wide section in plan view. The first scan line has a second wide section. The second signal line has a pair of third wide sections, and the second signal line intersects the second wide section of the first scan line at the pair of third wide sections in plan view. The first wide section of the first signal line is opposite to the second signal line between the pair of third wide sections without being opposite to the pair of third wide sections.

A display device includes a first substrate having a pad, a second substrate having a shield conductive layer, and a conductor connected to the pad and the shield conductive layer. The first substrate includes a first wiring provided under the pad and the pad includes an organic insulation film provided so as to cover the first wiring and a transparent conductive film provided over the organic insulation film. The transparent conductive film includes a first transparent conductive film provided over the organic insulation film and a second transparent conductive film connected to the first transparent conductive film. The first transparent conductive film is provided so as to avoid an upper part of the first wiring in a plan view and the second transparent conductive film is provided so as to cover the first wiring and the first transparent conductive film in a plan view.
