DEFINITION

Classification: 349/84

Having significant detail of cell structure only:

(under subclass 56) Subject matter including a specific aspect of the structure which surrounds the liquid crystal material.

(1) Note. Included here is structure involving the liquid crystal material, structure immediately adjacent to the liquid crystal material, and structure attached to the structure adjacent to the liquid crystal material.
