the display sub-pixel unit of the first color is configured to emit light for display of a displayed image, and the disturbing sub-pixel unit of the first color is configured to emit light for display of a disturbing image;
the first optical film sheet includes a first sub-optical-film unit provided correspondingly on the display sub-pixel unit of the first color and configured to allow the transmission of light emitted by the display sub-pixel unit of the first color, and a second sub-optical-film unit provided correspondingly on the disturbing sub-pixel unit of the first color and configured to allow transmission of light emitted by the disturbing sub-pixel unit of the first color, and the first sub-optical-film unit and the second sub-optical-film unit being arranged to allow polarization states of lights emitted from the first sub-optical-film unit and the second sub-optical-film unit to differ from each other; and
the first sub-optical-film unit is configured to allow a transmitted light to be a non-polarized light, and the second sub-optical-film unit is configured to allow a transmitted light to be a polarized light, polarization states of lights for displaying two kinds of images differ from each other, the polarized light that forms the disturbing image is removed by a pair of glasses with polarizers, and the light that forms the displayed image is at least partially transmitted, so as to provide a user with a normal displayed image.

2. The display device according to claim 1 , wherein the second sub-optical-film unit is configured to allow a transmitted light to be a linearly polarized light.

3. The display device according to claim 1 , wherein the display sub-pixel unit of the first color and the disturbing sub-pixel unit of the first color are adjacent to each other in a longitudinal direction or a lateral direction of the display panel.

4. The display device according to claim 1 , further comprising a driving circuit connected with the sub-pixel units, wherein the driving circuit is configured to control a display grayscale of the display sub-pixel unit of the first color and a display grayscale of the disturbing sub-pixel unit of the first color.

5. The display device according to claim 4 , wherein the driving circuit is configured to allow the display grayscale of the display sub-pixel unit of the first color and the display grayscale of the disturbing sub-pixel unit of the first color to be complementary with each other.

6. The display device according to claim 4 , wherein the display grayscale of the disturbing sub-pixel unit of the first color has a first fixed value; or
difference between the display grayscale of the display sub-pixel unit of the first color and the display grayscale of the disturbing sub-pixel unit of the first color has a second fixed value.

7. The display device according to claim 1 , wherein at least one of the pixel units further includes at least one sub-pixel unit of other color in addition to the sub-pixel unit of the first color.

8. The display device according to claim 7 , wherein at least one of the sub-pixel units of other colors includes a display sub-pixel unit and a disturbing sub-pixel unit corresponding to its color; and
the first optical film sheet includes sub-optical-film units disposed corresponding to the display sub-pixel unit and the disturbing sub-pixel unit, respectively, so that polarization state of light passing through the display sub-pixel unit and the first optical film sheet and polarization state of light passing through the disturbing sub-pixel unit and the first optical film sheet differ from each other.

9. A display system, comprising:
