The present invention provides a display device which includes signal lines which are formed on an upper surface side of a substrate, an insulation film which is formed such that the film covers the signal lines except for terminal portions of the signal lines, and conductive layers which extend in the extension direction of the signal lines such that the terminal portions traverse the terminal portions. In such a display device, gaps are formed between respective sides of the conductive layer parallel to the extension direction of the conductive layer and the insulation film and holes are formed in the signal lines at portions corresponding to the gaps along the extension direction of the signal lines.
