Abstract

A touch display device and a manufacturing method thereof are provided. The touch display device has a touch sensing area and a virtual touch area, and comprises a first and a second metal layer, filter layers, and common electrode layers. The first metal layer is arranged below an upper glass substrate, and the first metal layer includes a first touch line that is located in the touch sensing area; the second metal layer is arranged below the first metal layer, and includes a second touch line and a second virtual line, wherein the second touch line is located in the touch sensing area, the second virtual line is located in the virtual touch area, and the second touch line and the first touch line form a touch sensing element; the filter layer located in the touch sensing area covers the second touch line, and the filter layer located in the virtual touch area does not cover the second virtual line; and the common electrode layer located in the touch sensing area is not in contact with the second touch line, and the common electrode layer located in the virtual touch area is in direct contact with the second virtual line to reduce the resistance of the common electrode layer. The present invention also discloses a manufacturing method for the touch display device.

Description
