A display device having a liquid crystal display element ( 30 ) transmitting light projected from a light source to an watching point side, and including pixels ( 31 ) forming a first image region and a second image region, and an image separation filter ( 32 ) disposed from the pixels ( 31 ) through glasses ( 33, 34 ) each with a specified thickness and forming a first image separation mechanism and a second image separation mechanism, in which a calculation for obtaining the disposing interval (P 1 , P 3 ) of each of the above-described image separation mechanisms of the image separation filter ( 32 ) is carried out on the basis of angles of elevation thetak+1, thetak, angles alphak+1, alphak, thicknesses W 1 , W 2 and refractive index n of the glasses ( 33, 34 ), a distance D from the watching point to the display device, and an interval (P 2 ) between the image regions of the above-described pixels ( 31 ) to dispose the image separation mechanisms of the above-described filter ( 32 ) with the obtained P 1 , P 3.
