The foldable device may include a foldable (or bendable) display or a flexible display, and may be folded or unfolded to be used. A rollable device or a slidable device may include a flexible display, and may be roll and receive the flexible display in a rear surface of the slidable device or extend the flexible display to a front surface to be used. An electronic apparatus including a display having a designated size may include one digitizer layer and one touch layer on the display. The electronic apparatus may include a touch layer below a display and a digitizer layer below the touch layer. A slidable electronic apparatus may include a flexible display and a touch layer in the front surface of the flexible display. The touch layer may be bendable and thus may be arranged in one layer corresponding to the flexible display. However, the digitizer layer may be not bendable and thus may be difficult to arrange as one layer corresponding to the flexible display.
