A display apparatus includes a display device, a touch panel, and a control device. The control device acts as a display controller. The display controller causes the display device to display an operation screen including a character input field, superimpose a keyboard on the operation screen, when the touch panel receives a touch operation performed on the character input field, and display a first scroll bar for scrolling the operation screen, a displayed portion of which has been reduced by the keyboard superimposed, in a first vacant region in the reduced displayed portion, not overlapping with the character input field and the keyboard.
