What edge was set up.The angle provided by the embodiment of the present invention is set, and more convenient can go to drive liquid with drive cycle
Liquid crystal molecule in crystal layer.
Further, it is contemplated that the good characteristic of glass and extensively using property, the embodiment of the present invention it is preferred by the first base
Plate 11, the substrate 33 of second substrate 22 and the 3rd select to be glass substrate.
Further, the first friction orientation in the embodiment of the present invention is to drive hair wheel cloth to carry out first by rubbing machine to rotate
Obtain, the second friction orientation drives hair wheel cloth to carry out the second rotation and obtained by rubbing machine.
Specifically, the embodiment of the present invention uses suede cloth-like material friction orientation layer surface in a certain direction, to cause liquid
Liquid crystal molecule in crystal layer can be arranged along the frictional direction of both alignment layers in the future, it is ensured that the uniformity of Liquid Crystal Molecules Alignment.Its
In, the validity of friction has been taken into account in process so that the friction process on two sides is independent of each other, accordingly, it is preferred that using
It is two-sided at the same processing mode, to prevent destruction of the secondary operation to processing first.In addition, after orientation friction, glass substrate
On have the pollutants such as some flannelette lines, it is necessary to rinse out pollutant by special cleaning flow.Clear to glass substrate
Wash after finishing, carry out fluid sealant coating, its purpose is to allow between adjacent glass substrate be adhesively fixed, while can also prevent liquid
Crystalline substance outflow.
