A head-up display includes: a display panel emitting image light corresponding to a parallax image including a left-eye image and a right-eye image; a barrier including barrier patterns allowing the 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 carrying out focusing of the image light corresponding to the parallax image and projecting 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 and second enlargement factors are different from each other.
