Abstract
The present invention discloses a display panel substrate assembly and an apparatus and method for forming a display panel substrate assembly, wherein the substrate assembly includes a first substrate and a second substrate. At least one of the first substrate and the second substrate is optically clear. The method includes the steps of screen printing a non-sag adhesive composition onto a surface of the first substrate, bringing the non-sag adhesive composition into contact with a surface of the second substrate in an environment having a pressure of less than or equal to about 5000 pascals, and curing the non-sag adhesive composition to yield an adhesive layer. The non-sag adhesive composition is of a type which is optically clear after curing.
