Zusammenfassung:The disclosure provides a screen anti-peeping protection layer arranged above a display panel. The screen anti-peeping protection layer includes a first polarizing layer, a second polarizing layer, a viewing angle adjusting layer and a touch sensing layer. The first polarizing layer and the second polarizing layer are sequentially arranged on a transmission path of a display beam which comes from the display panel. The viewing angle adjusting layer is arranged on the transmission path and located between the first polarizing layer and the second polarizing layer, and used for changing a range of an emitted light viewing angle of the display beam. The touch sensing layer is arranged on the transmission path, and located above the viewing angle adjusting layer and opposite to the first polarizing layer. The disclosure also provides a touch display device including the screen anti-peeping protection layer and the display panel as described above.
