Abstract:
A method of aligning a pair of liquid crystal display substrates such that a resulting alignment of a first substrate with respect to a second substrate completes a pixel and electrical contact between both substrates to allow for liquid crystal display operation, comprising the steps of:a) depositing a plurality of magnetic field-generating elements at selected locations on a first surface of a first substrate, b) depositing a plurality of magnetic field-detecting elements on a second surface of a second substrate at locations corresponding to said selected locations, c) joining the substrates together into approximate alignment of said first substrate with said second substrate to permit a field interaction between corresponding field-generating and field-detecting elements to complete alignment between said first substrate and said second substrate so that the first surface faces the second surface; and d) depositing a selected quantity of liquid crystal material in a central region of one of the first surface and the second surface, wherein the magnetic field-generating and magnetic field-detecting elements are located outside the central region.
