Polarization controlling elements

A method of manufacturing a liquid crystal display assembly comprising:

• a) providing a transparent substrate;
• b) depositing the LPP layer on one side of the transparent substrate;
• c) exposing the LPP layer to linearly polarized light for aligning LPP molecules therewith;
• d) depositing the LCP layer on the LPP layer forming a coated sample;
• e) annealing the coated sample to accelerate alignment of the LCP layer with the LPP layer;
• f) curing the coated sample by exposing the coated sample to ultra-violet or e-beam radiation
• g) reducing an in-plane ΔN birefringence value of the LCP layer between 0.0001 and 0.14 in the blue portion of the visible spectrum and between 0.0001 and 0.104 in the red portion of the visible spectrum;
• and
• h) mounting the coated sample on a liquid crystal display panel.

A method of manufacturing a trim retarder comprising:

• c) exposing the LPP layer to linearly polarized light for aligning LPP molecules therewith;
• d) depositing the LCP layer on the LPP layer forming a coated sample;
• e) annealing the coated sample to accelerate alignment of the LCP layer with the LPP layer;
• f) curing the coated sample by exposing the coated sample to ultra-violet or e-beam radiation;
• and
• g) reducing the in-plane ΔN birefringence value of the LCP layer to less than 0.07 in the visible spectrum.
