A visual display with an alignment structure for visually determining a correct display angle and lateral displacement, top to bottom and left to right, for accurate color viewing. A first fixed pattern is located on a surface near a border of the display and a spacer supports a plate, elevated above the first pattern, having a second pattern around a throughole in the plate. The dimensions of the first and second patterns, the elevation of the second, and the throughole diameter are such that when viewed at the intended display angle the image of the first pattern is concentric with the image of second pattern. Alternatively, the spacer may be formed of a transparent member with the second pattern on a planar surface above and parallel to the first fixed pattern. A first and a second alignment structure may be located symmetrically about either side of the display to enable determination of lateral alignment as well as angle of the display.

[ Having thus described my invention, what I claim as new and desire to secure by Letters Patent is as follows:] [1.] A visual display alignment apparatus, comprising:a pattern support;first visual pattern arranged in a first plane on said pattern support, having a first perimeter having a first diameter, said first perimeter arranged in symmetrical alignment with a center point on said pattern support;means for supporting a second pattern in a second plane a first distance in a first direction away from an upper surface of said first pattern, said second plane being substantially parallel to said first plane;a second pattern formed in said second plane on said means for supporting a second pattern, said second pattern having a second perimeter having a second diameter, said second perimeter arranged in symmetrical alignment with an alignment axis normal to said display plane and passing through said center point,wherein said first diameter, said first distance, said second diameter and said means for supporting a second pattern are arranged such that a projection of said first pattern and said second pattern on a plane normal to said first direction spaced apart from outer pattern provides an image of a substantially concentrically aligned first perimeter of said first pattern and said second perimeter of said second pattern around said alignment axis.
