The invention discloses a display dust cover with a privacy protection function which comprises a rectangular frame, and a transparent dust-proof membrane is arranged on the rectangular frame; a left baffle plate and a right baffle plate are arranged at the two ends of the rectangular frame respectively, the lower end of the left baffle plate and the lower end of the right baffle plate are each provided with a pivot rotatably matched with the rectangular frame, and the upper end of the left baffle plate and the upper end of the right baffle plate are each provided with a screw matched with the rectangular frame in a threaded mode. According to the display dust cover with the privacy protection function, the dust-proof membrane is fixed through the rectangular frame, so that the dust-proof membrane can stably keep smooth, and the phenomenon that the display effect is affected due to the corrugation of the dust-proof membrane does not occur; the left baffle plate and the right baffle plate are arranged at the two ends of the rectangular frame, due to the fact that the left baffle plate and the right baffle plate can be turned to the required angles by loosening the screws when a computer is used, so that peeping at the display by others is avoided, the function of protecting the privacy is achieved, and the problem that unclear display of the display caused by light reflection is avoided.
