An infrared communication system is disclosed, that has a transmitter and a receiver. The transmitter includes a modulator, a first converter, an infrared transmission section. The modulator modulates a first electric signal and generates a second signal as a modulated signal. The first converter converts the second signal into an infrared signal. The infrared transmission section transmits the infrared signal to the receiver. The receiver includes a filter, a second converter, and a demodulator. The filter restrains rays having a spectrum whose peak is present at a predetermined wavelength emitted by a plasma display panel. The second converter converts the infrared signal passed through the filter into a third electric signal. The demodulator demodulates the third electric signal.
