Abstract

In a process for applying orientation layers to cell plates (11.o, 11.u), the cell plates are arranged in relation to a centrifuge rotational axis (14) so that the plate planes lie parallel to the rotational axis. The centrifugal forces then act over the entire plate surfaces in the same direction in each case. This leads to a homogeneous pre-alignment of the orientation layer molecules. Because a homogeneous pre-alignment of orientation layer molecules can be achieved with this process, an improved orientation effect can be obtained.
