Claim 12:
13. An optical structure that is an intermediate work product of a compound light-guide optical element (LOE) fabrication process, the optical structure comprising:
a first region comprising a plurality of LOE precursors, each LOE precursor comprising a pair of major parallel surfaces and a first plurality of mutually parallel partially reflective internal surfaces angled obliquely relative to the pair of major parallel surfaces;
a second region comprising a second plurality of mutually parallel partially reflective internal surfaces being non-parallel to the first plurality of partially reflective internal surfaces; and
a third region separating the first and second regions, the third region being formed from a transparent plate having major external surfaces that are perpendicular to the pairs of major parallel surfaces.
