1. A display device, comprising a display panel and a time-of-flight (TOF) sensor arranged at a side of the display panel away from a display surface, wherein detection light received by the TOF sensor is allowed to pass through a target light-transmitting region of the display panel, wherein a light reflection interference layer is arranged on a surface of the target light-transmitting region facing the TOF sensor, and configured to adjust a transmission direction of reflected light between the display panel and a lens of the TOF sensor, and configured to ensure that reflectivity of the light reflected by the light reflection interference layer is within a preset range and ensure that the light received by the TOF sensor is not coherent light, wherein the preset range is greater than zero and less than or equal to 1%.
