Provided is a display device that ensures both of the conductivity for realizing the antenna function and the light transmissivity for transmitting light that forms a video image displayed on the display device, and at the same, allows short-range wireless communication to be performed in a wide range in a display section of the display device. A display deviceincludes a display panelan antenna patternfor driving, and antenna patternsA,B for propagation. The antenna driving unit drives the antenna patternfor driving, at predetermined carrier wave frequency, whereby the antenna patternfor driving and the antenna patternA orB for propagation are electromagnetically coupled. As a result, proximity wireless communication can be performed in a wide range of a display area ARof the display device

A digital optical transmitter includes a main/subdata modulation part for distorting a main data modulated signal waveform in response to sub-data, and an E/O conversion part for converting a subsequently obtained electrical modulated signal to an optical modulated signal and outputting the optical modulated signal. A digital optical receiver includes an O/E conversion part for receiving the optical modulated signal, converting it to an electrical modulated signal, and outputting the electrical modulated signal. Additionally, the digital optical receiver further includes a main/subdata demodulation part for demodulating the main data from the electrical modulated signal, while detecting whether or not a distortion signal responsive to the subdata is superposed on a subcarrier which forms the electrical modulated signal. If the distortion signal is superposed on a subcarrier, the main/subdata demodulator part demodulates the associated subdata.

An information managing device capable of systematically managing object data of more than one kind using a single database, having an object managing unit for storing the object data of more than one kind in general format, and a filter managing unit for storing a filter which specifies a specific format for each kind of object data. When the object data are registered, a control unit converts the object data the user has inputted in its specific format into those in general format to store the converted object data into the object managing unit. On the other hand, when the object data are retrieved, the control unit converts the object data in general format into those in specific format using the filter of the same kind as the desired object data.
