A display network module of the display apparatus is connected to the electronic appliance network module via a network and receives the alarm data. A display control unit stores the alarm data in a storage if the alarm data are received via the display network module and controls the display of a predetermined alarm message which corresponds to the alarm data to notify the reception of the alarm data on a portion of the display. The alarm data can be displayed on a screen while the user views a displayed image without the displayed image being shielded by the alarm data which could abruptly appear on the currently displayed screen.
