Abstract

A method for producing a display unit includes: inserting a covering glass into a first holder of a positioning device until the covering glass lies on a first contact surface parallel to the covering glass; thereafter inserting a bonding frame into a second holder of the positioning device until the bonding frame lies on a second contact surface parallel to the first contact surface. The bonding frame has a leg parallel to the covering glass, the peripheral edge of which leg directed toward the covering glass surrounds the peripheral edge of the covering glass at a distance forming a groove. Thereafter the groove between the covering glass and the leg of the bonding frame is filled with a first adhesive that connects these two parts to each other, and thereafter the surface of the covering glass facing away from an observer is covered with the layer of transparent bonding mass.
