Abstract

The present invention provides a cellular phone which includes a function for changing the viewing angle of the display section according to the specified executing function, when the cellular phone receives a user'"'"'s operation to specify the executable function through the operating section 115. The storage section 120 stores the viewing angle information table which associates the cellular phone'"'"'s function with viewing angle information. The designation to specify the executing function is received from the user through the operating section 115. The viewing angle change control section 10 reads out the viewing angle information corresponding to the specified function from the table, and executes the process of changing viewing angle according to the present viewing angle information in the viewing angle information storage section 1.

Claims
