Abstract: According to one embodiment, a display device includes a display portion including a first electrode, a second electrode, first pixel electrodes overlapping the first electrode, and second pixel electrodes overlapping the second electrode, first wiring lines connected to the first electrode, second wiring lines connected to the second electrode, and a control unit electrically connected to the first wiring lines and the second wiring lines. The display portion has a first end portion farthest from the control unit and a second end portion nearest to the control unit. The first electrode is adjacent to the first end portion. The second electrode is adjacent to the second end portion. The number of first wiring lines is a same as the number of second wiring lines.

Abstract: In an IPS-mode liquid crystal display device, the area of a terminal portion is decreased. A liquid crystal display device includes a TFT substrate and a counter substrate attached to the TFT substrate with a sealing material, and includes a display region and a terminal portion formed on the TFT substrate. A shielding transparent conductive film is formed on the outer side of the counter substrate. On the terminal portion, an earth pad formed with a transparent conductive film is formed on an organic passivation film. The shielding transparent conductive film is connected to the earth pad through a conductor. Below organic passivation film of the terminal portion, a wire is formed.
