Patent ID: 7786962

Claim:
An image display device comprising: a display panel which includes a plurality of display pixels arranged in a matrix, each display pixel having an M×N sub-pixel matrix which is formed within a square area wherein M and N each represent a natural number; and a lenticular lens which has a plurality of cylindrical lenses arrayed along array direction of N number of sub-pixels, each of said cylindrical lenses corresponding to N number of sub-pixels, in said each display pixel; wherein the image display device is configured such that: n ×sin α=sin β; OD ×tan β= e; n ×sin γ=sin δ; OD ×tan δ= m×L ; and p ×tan γ=( N×m×p−m×L )×tan α; wherein an array pitch of said cylindrical lenses is L; wherein a pitch of said sub-pixels in a direction orthogonal to a longitudinal direction along a ridge projection of said lenticular lens is P; wherein a refractive index of said lenticular lens is n; wherein an observation distance between said lenticular lens and an observer in a maximum three-dimensional visible range is OD; wherein a width over which a pixel is projected in a magnified form at an observation distance D is e; wherein a number of said sub-pixels between a central portion of a display pixel comprising sub-pixels for left and right eyes located at a central portion of said display panel, and a central portion of a display pixel located at an end portion of said display panel is 2 m; wherein an incident angle and an exit angle of light at an apex of one of said cylindrical lenses located at said central portion of said display panel are α and β, respectively; and wherein an incident angle and an exit angle of light at an apex of one of said cylindrical lenses located at said end portion of said display panel are γ and δ, respectively.
