DEFINITION

Classification: 349/160

With particular topology (i.e., other than for diffraction and spacers):

(under subclass 158) Subject matter wherein a surface of the substrate is nonplanar, but wherein the nonplanar surface is not used for diffraction or as a liquid crystal spacer.

(1) Note. Included here are curved or roughened surfaces.

(2) Note. The nonplanar surface is not used for diffraction or as a liquid crystal spacer.
