A device structure for single cell gap reflective and transflective liquid crystal displays (TF-LCDs). For an entirely reflective LCD, the imbedded wire-grid polarizer (WGP) serves as a polarization-dependent for the ambient light. For a transflective TF-LCD, the WGP only covers the reflective pixels. The disclosure also includes a method of using single cell gap liquid crystal displays (LCDs) without phase retardation films by providing a single cell gap LCD having reflective pixels and transmissive pixels, covering solely the reflective pixels, with at least one of: a wire grid polarizer and a broadband cholesteric reflector (BCR), reflecting ambient light off the reflective pixels; and passing back light through the transmissive pixels whereby the cell gap LCD obtains high contrast ratios without using phase retardation films.
