Glass lenticulars for autostereoscopic display

A forming body for forming a lenticular array on a sheet of glass, the forming body comprising:

• a base member and a plurality of elongate projections protruding therefrom, the plurality of projections arranged as substantially parallel walls, each of the elongate projections comprising a distal end and a root end, each elongate projection further comprising a height Hp defined as a distance from the root end of the elongate projection to the distal end in a direction normal to a plane of the base member;
• and
• wherein a thickness of the distal ends is equal to or less than 5 μm.

A glass lenticular array comprising:

• a base portion;
• and
• rows of cylindrical lenses protruding from the base portion, the cylindrical lenses and the base portion formed as a single-piece, the lenses spaced apart from one another by depressed regions between adjacent cylindrical lenses, each of the depressed regions covered with dark material.
