Abstract: A method for manufacturing a gelatin-coated glass panel is described. In this, gelatin is first applied onto a glass panel, then a protective layer is sputtered on through a mask placed onto the gelatin layer. After removal of the mask, the gelatin can be removed, with the aid of a dry etching method, from the regions in which it is not equipped with a protective layer. The glass panel can then easily be divided by scoring and breaking. The method makes it possible to produce, on a large-scale production basis, liquid crystal displays which have either a color filter or a black matrix made of photoemulsion.

Abstract: A dispenser (1,1a) provides for filling a dosing chamber (15,15a) by gravity and then emptying it by closing an inlet valve (39,39a), by opening an outlet valve (40,40a) and by shortening the dosing chamber (15,15a) with the assistance of air flow through a discharge port (7,7a) and into a cup (80) which in one embodiment is assembled as part of the dispenser (1a) and which is removable so that its medium contents can be dispensed. Such a dispenser (1,1a) achieves a highly accurate dosing with simple handling and construction.
