- the manner mode control unit 22 determines whether or not the mana mode setting has been changed, and the application The application control unit 21 determines whether or not the force has been changed (S12). If there is no change in both manner mode setting and application setting (NO in S12), return to step S10 and repeat the above operation.
- the manner mode setting'application setting is changed (YES in S12)
- data indicating that the setting has been changed is sent to viewing angle search unit 24.
- the viewing angle search unit 24 searches the correspondence table 50 for the viewing angle corresponding to the combination of the changed manner mode setting and application setting (S13).
- the viewing angle control unit 25 controls the viewing angle changing unit 32 so that the retrieved viewing angle is obtained (S14).
- the viewing angle can be controlled in accordance with the operation mode and the operation state of the application. Then, return to step S10 and repeat the above operation.
- the cellular phone 1 that is effective in the present embodiment has a configuration depending on whether or not the manner mode is set and whether or not a specific application is activated.
- the viewing angle can be controlled automatically.
- the viewing angle of the mobile phone 1 can be controlled independently of either the manner mode setting or the application setting.
- the viewing angle control unit 25 force manner mode setting or application setting is changed, Information regarding the setting change is directly received from the neural mode control unit 22 or the application control unit 21, and the viewing angle may be changed based on a predetermined setting without using the correspondence table 50.

- a medium viewing angle mode in which the viewing angle is neither wide nor narrow may be provided. This viewing angle mode is suitable for viewing the display screen by a few people including the user.
- the narrow viewing angle mode is set when the input button group 8 is operated.
- the user may accidentally operate the input button group 8. Therefore, it is troublesome for the user to change from the wide viewing angle mode to the narrow viewing angle mode each time. Therefore, it may be set so that the narrow viewing angle mode is set when the input button group 8 is operated a predetermined number of times or more in a predetermined period.
- the mode state in which an incoming call is notified by vibration (that is, the state in which the vibrator 41 is activated) is set to the manner mode, and the mode state in which an incoming call is notified by sound (ie, sound Force in which generator 42 is in a non-manner mode
