Display device and method of designing display device
First Claim
1. A display device having a transparent display element transmitting light projected from a light source to a watching point side, 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 display device 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 pixel member, 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 pixels, 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.

Abstract
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 (P1, P3) 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 θk+1, θk, angles αk+1, αk, thicknesses W1, W2 and refractive index n of the glasses (33, 34), a distance D from the watching point to the display device, and an interval (P2) 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 P1, P3.
