1. A display panel, comprising:
- a display functional portion formed such that a display functional layer is sandwiched between a first substrate located on an observer side and a second substrate located opposite to said observer side; and
a touch screen portion that includes a lower wire and an upper wire made of a conductive metal material, that includes an interlayer insulating film located between said lower wire and said upper wire, and that includes a protective film covering said lower wire, said upper wire, and said interlayer insulating film, whereinsaid first substrate has a first surface on said observer side and a second surface opposite to said first surface, andsaid lower wire of said touch screen portion is formed on said first surface of said first substrate and said upper wire is formed above said lower wire and said first surface of said first substrate, andan arrangement interval between said upper wire and said lower wire in plan view is smaller than a thickness of said first substrate and is between 0.1 mm to 1 mm.

Abstract
A display panel includes: a display functional portion formed of a display functional layer sandwiched between transparent substrates facing each other; and a touch screen portion that includes lower wiring and upper wiring made of a conductive metal material, that includes an interlayer insulating film located between the lower wiring and the upper wiring, and that includes a protective film covering the lower wiring, the upper wiring, and the interlayer insulating film. The lower wiring of the touch screen portion is formed on a surface on an observer side of the transparent substrate on the observer side.
