Disclosed are various reverse-mode direct-view liquid crystal displays employing a liquid crystal having a characteristic wavelength in the non-visible spectrum, including reflective, transmissive and reflective-transmissive mode displays. In accordance with the principles disclosed, a direct-view liquid crystal display (LCD) includes a front substantially transparent substrate, a rear substrate, and a controllable cholesteric liquid crystal (CLC) disposed between the front and rear substrates and having a characteristic wavelength to reflect non-visible spectrum; the portions of the controllable CLC can selectively exhibit a planar state or a focal-conic state, the portions of the CLC in the planar state appearing dark, and the portions of the CLC in the focal-conic state appearing bright, to an observer of the LCD. The reflective, transmissive and reflective-transmissive mode displays are derived by further combinations with linear and/or circular polarizers, reflective mirrors and/or transmissive/reflective mirrors, and a source of visible light.

Reverse-mode direct-view display employing a liquid crystal having a characteristic wavelength in the non-visible spectrum

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.
