A head-up display includes: a display panel which emits image light corresponding to a parallax image comprising a left-eye image and a right-eye image; a barrier including barrier patterns which allows image light corresponding to the left-eye image and the right-eye image to reach user's left and right eyes, respectively; and an optical system which carries out focusing of the image light corresponding to the parallax image and projects a resulting parallax image to user's left and right eyes. The optical system carries out focusing of the image light corresponding to the parallax image on a projection plane so that the parallax image is enlarged in a first direction corresponding with a parallax direction by a first enlargement factor, and the parallax image is enlarged in a second direction intersecting with the first direction by a second enlargement factor. The first enlargement factor and the second enlargement factor are different from each other.
