Abstract
The present invention discloses a touch display device and a manufacturing method thereof, the display device comprising: an OLED display layer disposed on a lower substrate; an upper substrate; an air layer formed between the upper substrate and the lower substrate; and a touch module, disposed above the OLED display layer, wherein the touch module comprises: a first sensing circuit layer and a second sensing circuit layer, further wherein the first sensing circuit layer and the second sensing circuit layer are spaced and the distance between them is more than 2 μm. The display device can reduce interference in detection circuit caused by coupling capacitance formed between the sensing circuit layers thereby improving accuracy of touch detection.
