Abstract: The present invention provides a display device which has a display unit on a main body, comprising a cover member that can be deformed into a first shape for covering the display unit and a second shape for forming a grip in order to solve the problems in the conventional cameras. The problem is such that the size of the camera becomes large by the size of the grip, which impairs portability of the camera because the conventional camera provides a fixed grip on the camera body on which a display unit with a large screen is mounted. In addition, another conventional camera has a space for accommodating the cover members within the grip, so that the size of the grip becomes accordingly large and thus the camera itself becomes large.
