Abstract:
1. A structure comprising: a first substrate having a first surface and a second substrate having a second surface facing the first surface; liquid crystal material disposed between the first and second surfaces; a first upstanding electrode disposed over the first surface and extending into the liquid crystal material towards the second surface; and a first planar electrode disposed upon the first surface and electrically connected with the first upstanding electrode, the first planar electrode at least partially surrounding the first upstanding electrode, where a combination of the first upstanding electrode and the first planar electrode forms at least a portion of a pixel of a liquid crystal display; where a first sidewall of the first upstanding electrode is a tapered sidewall disposed at other than 90° to the first surface and where a second sidewall of the first upstanding electrode that is opposite to the first sidewall of the first upstanding electrode is a vertical sidewall disposed at 90° to the first surface; where the first upstanding electrode is comprised of a non-electrically conducting core that is coated with an electrically conductive material on a top surface thereof and on the tapered first sidewall but not on the vertical second sidewall.
