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.

Abstract: A liquid crystal display device includes a panel unit and a driving unit driving the panel unit. The driving unit includes as operation modes a first mode in which a detection operation of a first external object is performed in units of a divided region obtained by dividing an entire surface of a touch region of the panel unit and a second mode in which a detection operation of a second external object is performed on the entire surface of the touch region of the panel unit. The first mode is a mode detecting, in units of the divided region of the panel unit, a contact position of the first external object with each divided region, and the second mode is a mode detecting, on the entire surface of the panel unit, whether or not the second external object approaches the entire surface.

Abstract: In a transistor substrate of a display device, a plurality of signal lines to which any one of drive signals of a gate signal and a video signal is supplied include a plurality of first signal lines to which the drive signal is supplied. The first signal line is connected to a driving driver, and is formed in an edge region positioned between an end portion of a substrate and a pixel region and in the pixel region. The first signal line is formed to pass through a first wiring formed in a first layer from a second wiring formed in a second layer in the edge region.
