Touch-sensitive device and fabrication method thereof and touch-sensitive display device

A touch-sensitive display device, comprising:

• a touch-sensitive device having a touch-sensitive region and a non-touch-sensitive region and comprising:
• a transparent substrate;
• a touch-sensing structure disposed on the transparent substrate, located in the touch-sensitive region, and comprising a plurality of first sensing series and a plurality of second sensing series;
• a metal trace layer disposed on the non-touch-sensitive region;
• a transparent conductive layer disposed on the transparent substrate, located in the non-touch-sensitive region, and electrically connected to the metal trace layer;
• and
• a first insulation layer disposed on the transparent substrate and covering the touch-sensing structure, the metal trace layer and the transparent conductive layer, wherein at least one opening is formed on the first insulation layer to expose a part of the transparent conductive layer;
• and
• a display device in combination with the touch-sensitive device.

A fabrication method of a touch-sensitive device, comprising the steps of:

• providing a transparent substrate;
• forming a decorative layer on the transparent substrate;
• forming a metal trace layer on the decorative layer;
• forming a transparent conductive layer on the transparent substrate, wherein the transparent conductive layer is patterned to form a plurality of first sensing series and a plurality of second sensing series in a touch-sensitive region of the touch-sensitive device and to form a transparent conductive layer in a non-touch-sensitive region of the touch-sensitive device;
• forming an insulation layer on the transparent conductive layer;
• and
• forming at least one opening on the insulation layer to expose a part of the transparent conductive layer to enable the transparent conductive layer to electrically connect with an external circuit.
