Abstract
Abstract An electronic apparatus includes an LCD device having at least one flexible portion, a main body having the front, rear, right and left sides, and a coupling member for coupling the LCD device to the main body. The LCD device have a screen size more than twice the total upper surface of the main body, and thus completely wrap the upper surface, the front side, and the bottom surface of the main body. The front side of the main body is rounded to allow the LCD device to bend without a sharp 90° angle, which would be stressful to the bent portion. The LCD device includes a liquid crystal cell, a reinforcement plate disposed on the liquid crystal cell, and at least two strip-shaped recesses formed by removing portions of the reinforcement plate in said at least one flexible portion.
