Abstract: PROBLEM TO BE SOLVED: To provide a portable terminal device in which display contents are made to be able to be discriminated while preventing the partial degradation of a display element even when the display contents of the screen of the device are not changed for a prescribed hour or more. SOLUTION: When a control panel 18 is not operated for a prescribed hour or more, a CPU(central processing unit) 31 reads out information for display expressing luminance in picture data which are stored in a video RAM(random access memory) 35 and reverses constituting bits of the information or shifts them in a direction in which luminance is lowered by the prescribed number of bits and it overwrites them in the video RAM 35.

As a result, an EL(electroluminescent) display 17 performs display whose luminance is reversed cyclically or performs display whose luminance is reduced.  Thus, it is possible to make the partial degradation of the display uniform and to lower the speed of the degradation of the display in this terminal device.
