1. An organic light-emitting diode (OLE)) touch display device, comprising:

  • an OLED display;

    a phase difference plate, a touch layer and a linear polarizer sequentially disposed on a light-emitting side of the OLED display, in which the linear polarizer and the phase difference plate are combined to form a circular polarizer; and

    a transparent water-oxygen barrier layer disposed between the OLED display and the phase difference plate,wherein the touch layer includes a touch pattern formed by a transparent conductive material,wherein the water-oxygen barrier layer includes;

    an organic layer and an inorganic layer sequentially disposed on the OLED display,wherein the OLED display includes an encapsulation layer, and a first photosensitive adhesive is disposed between the water-oxygen barrier layer and the OLED display to cover lateral surfaces and an upper surface of the encapsulation layer.
