Abstract
When image data is displayed on the display portion of a conventional mobile telephone, characters cannot be displayed thereon, and thus the image data and the characters cannot be simultaneously displayed. In a portable electronic device according to the present invention, a cover member having a first display device (101) for displaying an image (digital still image or the like) and a second display device (102) having a touch input operational portion (for displaying characters, symbols, or the like) are attached to each other so as to allow opening and closing.
