Abstract: A display apparatus includes a storage that stores a set period that is a period from the point of time when electric power supply starts to the point of time when a projection section starts displaying an image, a remote control that accepts operation, and a controller that changes the set period based on the operation accepted by the remote control, and the controller causes the projection section to start projecting the image after the electric power supply starts and the set period then elapses.
