A photo-write-type image display method photo-writes into an image display medium comprising a polarity display element and an optical switching element. The method includes applying a first polarity pulse to the image display medium to write a first display color into the image display medium, and applying a second polarity pulse to the image display medium while exposing the optical switching element to light, to write a second display color to the image display medium. In the applying of the second polarity pulse, voltage is applied to the polarity display element so that the first display color displayed in a non-exposure region of the image display medium is maintained after the applying of the second polarity pulse.
