Abstract:
1. A method for a reflective liquid crystal display, said method comprising the steps of: providing a first substrate that is substantially transparent; providing a second substrate that is substantially reflective and substantially parallel with said first substrate; and providing a liquid crystal fluid having a birefringence (Δn) and a negative dielectric anisotropy between said first and second substrates; providing a first liquid crystal alignment layer on said first substrate, said first liquid crystal alignment layer being proximate to said liquid crystal fluid, wherein molecules of said liquid crystal fluid that are proximate to the first liquid crystal alignment layer have a first pretilt angle from about 2 degrees to about 15 degrees and a first azimuthal direction; providing a second liquid crystal alignment layer on said second substrate, said second liquid crystal alignment layer being proximate to said liquid crystal fluid, wherein molecules of said liquid crystal fluid that are proximate to the second liquid crystal alignment layer have a second pretilt angle from about 2 degrees to about 15 degrees and a second azimuthal direction, the second azimuthal direction being substantially perpendicular to the first azimuthal direction; such that
