Abstract
A substrate for a multi-color liquid crystal display (LCD), an LCD having the substrate, and methods of manufacturing the substrate and the LCD. In one embodiment, the substrate includes: (1) a substantially planar base and (2) a cell wall structure, located on a surface of the base, that defines at least first and second sets of independent cells having corresponding independent fluid fill ports when the cell wall structure is bonded to an opposing substrate.
