A multi-depth display apparatus comprises: a display panel comprising pixels arranged to display first image and second images; and a direction changing layer arranged so that light forming said first and second images enters the layer and then exits the layer, wherein: in relation to the light forming said first image, the direction of the light is changed by the layer so that the light exiting the layer is changed in direction by a first angle relative to the light entering the layer; in relation to the light forming said second image, the direction of the light is changed by the layer so that the light exiting the layer is changed in direction by a second angle relative to the light entering the layer; and said first and second angles are different to create a difference in perceived depth between said first and second images when viewed by a user.
