Display device and manufacturing method thereof

A manufacturing method of a display device, comprising:

• providing a substrate;
• forming pixels on the substrate;
• providing a base layer on the pixels;
• forming a first conductive pattern on the base layer;
• forming a touch insulating layer, the touch insulating layer including contact holes overlapping portions of the first conductive pattern on the base layer, the contact holes exposing the portions of the first conductive pattern;
• forming conductive films within the contact holes and contacting the exposed portions of the first conductive pattern;
• and
• forming second conductive patterns on the touch insulating layer, wherein the second conductive patterns and the conductive films are comprised of a different material from each other,
• wherein a first portion of the second conductive patterns are disposed in the contact holes and are formed to be electrically connected to the first conductive pattern through the conductive films.

An electronic device, comprising:

• a display device comprising:
• a substrate;
• pixels disposed on the substrate;
• a base layer disposed on the pixels,
• a first conductive pattern disposed on the base layer;
• a touch insulating layer disposed on the base layer, the touch insulating layer including contact holes defined therein, the contact holes overlap portions of the first conductive pattern and exposing the portions of the first conductive pattern;
• second conductive patterns disposed on the touch insulating layer, and
• conductive films disposed within the contact holes and contacting the exposed portions of the first conductive pattern, the conductive films are comprised of a different material than the second conductive patterns,
• wherein a first portion of the second conductive patterns are disposed in the contact holes and are electrically connected to the first conductive pattern through the conductive films.
