Disclosed is a functional display type anti-blinding device having an anti-blinding plate (5) for indication and control of a screen display condition and variation in light transmittance. The anti-blinding plate includes a filter (110) to selectively filter light, a polarizer (120) to polarize the filtered light, a shutter LCD (130) having a variable light transmittance based on control of a light transmission control unit, a transparent dot-matrix LCD (140) to indicate the screen display condition based on control of a display control unit, and a glass protector (150) at the rear of the transparent dot-matrix LCD. The shutter LCD flickers several times to indicate an initial state and is turned off. The transparent dot-matrix LCD is turned on upon turn-off of the shutter LCD to indicate the screen display condition. The shutter LCD is turned on upon turn-off of the transparent dot-matrix LCD to transmit light based on preset light transmittance.
