Abstract
Optical elements are prepared by the adhesive transfer of at least a low temperature curable (e.g., radiation or room temperature curable) adhesive layer and a conductive layer to a substrate, preferably a transparent, non-birefringent substrate such as ceramic, glass or polymeric film having, for example, a color filter array thereon. The curable adhesive is cured after the curable adhesive layer has been placed into contact with a final receptor surface (e.g., a color filter array on a liquid crystal panel).
Claims18
A method for the manufacture of an optical element comprising in sequence, a color filter array, a crosslinked organic polymeric layer adhered to said color filter array, and a conductive layer, said process comprising the steps of:
- a) depositing a conductive layer onto a first substrate,
- b) depositing a layer of crosslinkable material onto said conductive layer,
- c) placing the layer of crosslinkable material into contact with the color filter array while said layer of crosslinkable material is in contact with said conductive layer,
- d) curing said crosslinkable material to adhere the layer of crosslinkable material to both the color filter array and the conductive layer, and
- e) stripping said first substrate from said crosslinkable material.
