In a head-mounted display (1), functions of a cross key (7) are displayed on a display section (6) immediately after the power is turned on, as shown in A in FIG. 1(a). The functions displayed are FF (fast forward), REW (rewind), Vol+ (increase sound volume), and Vol- (decrease sound volume), and thus, only the operation for changing voice information is possible. That is, the functions of the head-mounted display (1) immediately after the power is turned on are those for handling only the voice information, and functions for video information are not included in them. After the power is turned on, if the user desires video information, they push a push button switch (8). This causes video information, such as a music title selection screen, to be displayed as shown in B in FIG. 1(b), and operation of the cross key (7) provides a mode in which the content of video information can be changed. The display device facilitates operation when the user starts to use it. |
