An electronic device with a liquid crystal display (LCD), such as a foldable cellular phone, improves the visibility of the LCD by making the content displayed on the LCD visible even when the device is closed. The foldable electronic device includes: a display unit casing and an operating unit casing, which are connected by a hinge in a manner that allows each casing to rotate. The display unit housing is fitted with a projected LCD which is visible on both sides, and the operating unit housing has input keys. The device also includes a display control means for controlling whether the LCD needs to display reversed display content according to whether the user views the LCD from the front or from the back. A surface of the operation unit cabinet which is in face-to-face contact with the LCD when the device is folded is subjected to reflective processing for reflecting light to the LCD. In addition, a light source provided inside the operating unit for illuminating the input keys also illuminates the LCD when the device is folded.
