The information display device (10) includes: a display device (100a) etc. which transmit signals via electromagnetic waves; and a portable terminal (300). The portable terminal (300) includes: a reception measurement unit (330) that receives the signals from the display device (100a) etc. and measures an intensity of the signal; and a transmission unit (340) that transmits predetermined data and intensity data indicating a result of the measurement. The display device (100a) includes: a transmission unit (110a) that repeatedly transmits the signal via electromagnetic waves; and a display unit (130) that changes a display state according to the pieces of data transmitted from the portable terminal (300). The display unit (130) changes the display state to a first state where display information is displayed according to the predetermined data, when the intensity indicated by the intensity data is greater than a first threshold, and changes a value of the first threshold after the change of the display state.",
