The present disclosure provides a wearable display device that relates to the field of virtual reality technology. Because the wearable display device has a high efficiency in processing electric signals transmitted via each of the photoelectric sensor assemblies, the wearable display device can quickly determine a gaze position of eyes of a user on the display panel based on an electric signals transmitted via each of the photoelectric sensor assemblies. In this way, the efficiency of the display panel in displaying images is improved, and the refresh rate of the display panel is higher. Moreover, as the photoelectric sensor assembly receives an optical signal, reflected via the eyes of the user, via a target structure in s lens assembly, it is possible to avoid the optical signal received by each of photoelectric sensor assemblies from being transmitted from different structures, ensuring the reliability of the optical signal received by each of photoelectric sensor assemblies, and thus the accuracy of determining the gaze position.
