In the display device provided in the above-mentioned embodiment of the invention, specifically, the specific structure of the sub-pixel array 11 may be, as shown in fig. 5, the sub-pixel array includes a red sub-pixel unit R, a green sub-pixel unit G, and a blue sub-pixel unit B, the red sub-pixel unit R, the green sub-pixel unit G, and the blue sub-pixel unit B may be sequentially arranged in the row direction x of the sub-pixel array 11, and the color of each column of sub-pixel units 111 is the same in the column direction y of the sub-pixel array 11. The first polarization selection layer 3 on the red sub-pixel unit R adopts a cholesteric liquid crystal layer with the screw pitch consistent with that of red light, the first polarization selection layer 3 on the green sub-pixel unit G adopts a cholesteric liquid crystal layer with the screw pitch consistent with that of green light, and the first polarization selection layer 3 at the position of the blue sub-pixel unit B adopts a cholesteric liquid crystal layer with the screw pitch consistent with that of blue light.

And the second polarization selection layer 4 on the optical sensor 2 opposite to the second red sub-pixel unit adopts a left-handed cholesteric liquid crystal layer which does not allow the left-handed circularly polarized light emitted by the first red sub-pixel unit to enter, so that the light crosstalk between adjacent same-color sub-pixels is avoided. Along the row direction x of the sub-pixel array 11, the light emitted by two adjacent sub-pixel units of different colors passes through the filtering effect of the filter layer, so as to avoid the crosstalk of light among the sub-pixel units of different colors.
In the display device provided by the above embodiment of the invention, the optical sensor 2 may be a PIN photodetector.
In particular, as shown in fig. 8, the color filter layer 5 on the optical sensor 2 may be located on a side of the second polarization-selection layer 4 remote from the first polarization-selection layer 3.
In the display device provided by the above embodiment of the invention, as shown in fig. 9, the display panel 1 may specifically include a first electrode 12, a second electrode 13, and a light emitting layer 011 located between the first electrode 12 and the second electrode 13, where the light emitting layer 011 includes a plurality of light emitting regions arranged in an array, and each light emitting region corresponds to one sub-pixel unit.
