Abstract:
1. A method of designing a display device having a transparent display element transmitting light projected from a light source to an watching point, and comprising a pixel member formed with a first image region and a second image region, and an image separation filter separated from the pixel member by a specified region and formed with a first image separation mechanism and a second image separation mechanism, the designing method characterized in that a disposing interval of each of said image separation mechanisms is determined by carrying out a calculation for obtaining the disposing interval on the basis of an angle formed by a straight line connecting said watching point and an end point of the image region of said pixels, with respect to a perpendicular line from the watching point to the display device, a thickness and a refractive index of said specified region, a length of said perpendicular line, and an interval of the image regions of said pixel member, and the first and second image separation mechanisms of said image separation filter are arranged to cause light to be polarized in directions of polarization different from each other.
