The embodiment of the invention discloses a display panel, a display device and electronic equipment. The display panel comprises a display area; the display panel comprises a light sensor and a plurality of sub-pixels, wherein the light sensor and the sub-pixels are arranged in the display area; the display panel comprises a light sensing device layer and a display layer, and the sub-pixels are arranged in the display layer; the light sensing device layer is independent of the display layer, and the light sensor is arranged in the light sensing device layer; the light sensor comprises a transmitting unit and a receiving unit, the transmitting unit is used for transmitting infrared light to the environment of the display panel, and the receiving unit is used for receiving reflected light reflected by a measured object; the vertical projections of the transmitting unit and the receiving unit on the display layer are located in the sub-pixel projection gaps. Therefore, the light sensor is arranged in the gap of
