Method of manufacturing liquid crystal displays having an internal polarizer

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.
