In a process to manufacture a liquid crystal cell, one of the two plates is provided with an adhesive edge strip. A quantity of liquid crystal which is required to form the liquid crystal layer is applied to one of the two plates and the two plates are brought together and positioned in the vacuum and bonded tightly together by the adhesive curing. By the fact that the plates with the correct quantity of liquid crystal on one of the plates are joined together in the vacuum, it is no longer necessary to evacuate the inner space between the plates in a time-comsuming process and apply liquid crystal through a small filling hole in another time-consuming process.

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.

A self-supporting frame member mounts a cathode and a control grid in mutual electrical contact to form a unit module that can be secured to other similar unit modules to construct a multi-character vacuum fluorescent display.
