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.
Claims9
A display device comprising:
- a glass substrate;
- an interlayer insulating film;
- a capacitive insulating film;
- an earth pad having an organic passivation film and a transparent conductive film;
- and
- a first metal portion located directly under the organic passivation film of the earth pad,
- wherein the first metal portion is not connected to the transparent conductive film of the earth pad,
