Patent ID: 7002661

Claim:
A method for the manufacture of liquid crystal displays, each comprising a pair of facing plates coupled in such a way as to form a cell able to receive the liquid crystal; and a respective pair of polarizing layers associated with the plates, in which a plurality of plates is formed starting from an original sheet ( 10 ), the method being characterised in that it comprises the operation of application of a polarising layer ( 20 ) by deposition of a liquid crystal polarising substance and orientation of the molecules of the substance for determination of the polarisation axis; application of an alignment layer of polyimide resin onto the crystallised polariser layer ( 20 ) according to a predetermined configuration substantially corresponding to the display areas ( 30 ) of the devices; and subsequent selective removal of exposed portions of the polarising layer ( 20 ) from the separation regions between the display areas ( 30 ) of the devices, not masked by the alignment layer, the said operations being performed before the operations of coupling a pair of sheets ( 10 ) in facing position and subsequent separation of the individual cells.
