A traffic sign board easily identifiable during day and night is provided. The traffic sign board which is easily identified at night includes a flickering operation of a backlight installed inside a frame, and easily identified by a driver during day even on a secluded country road or a deserted road due to flickering of light emitting diode (LED) light projected to a front side through a reflective sheet while the backlight is switched off.
