| 1. A display device with a terminal portion on a substrate thereof, wherein the terminal portion comprises:
a first transparent conductive layer;
an insulation film which has an opening exposing a portion of the first transparent conductive layer, the opening enabling
insertion of a terminal for external equipment;
a second transparent conductive layer which is formed on at least a part of the portion of the first transparent conductive
layer which is exposed from the insulation film at the opening of the insulation film;
a plurality of conductive layers which are formed between the first transparent conductive layer and the second transparent
conductive layer at the opening of the insulation film, the respective conductive layers being formed in a same layer; and
a signal line which is formed between the insulation film and the first transparent conductive layer and is directly and electrically
connected to the first transparent conductive layer, the first transparent conductive layer being formed between the signal
line and the substrate.
