1. A wearable display device, comprising:
a display panel, comprising a display region and a peripheral region surrounding the display region;
a first light-emitting element, configured to emit light to be irradiated to eyes of a user;
a plurality of photoelectric sensor assemblies in the peripheral region, each of the photoelectric sensor assemblies being configured to receive an optical signal, reflected via the eyes of the user, of the first light-emitting element, and convert the optical signal into an electric signal, the electric signal being configured to determine a gaze position of the eyes of the user on the display panel;
a first polarizer layer, disposed on a light-emitting side of the first light-emitting element; and
a second polarizer layer, disposed on a side, distal from the display panel, of the photoelectric sensor assembly, a polarization direction of the second polarizer layer being intersected with a polarization direction of the first polarizer layer.
