Liquid crystal display and method of making

Claim 1

A method of operating a liquid crystal display including: providing a cell formed by front and rear plane parallel plates having electrode films formed on the inner surfaces thereof, at least the front plate having a transparent and segmented electrode film, wherein a polarizer is provided at the front plate but not at the rear plate, the cell having a reflector at the rear plate, wherein a liquid crystal of positive dielectric anistropy is disposed within the cell between the plates, the liquid crystal molecules exhibiting preferred directions at the inner surfaces of the front and rear plates, with the preferred directions rotated by about 90° to one another, the reflector being formed on the inner side surface of the rear cell plate between the front and rear cell plates and exhibiting a structure determining the preferred direction of the neighboring liquid crystals molecules, the front electrode segments being holohedral; and applying an operating voltage lying between 1.3 and 2.5 times the Freedericksz threshold voltage (V th ) across the electrodes formed on the front and rear cell plates such that the liquid crystal between the electrodes having the operating voltage applied thereacross retains an ability to rotate the polarization plane of light traversing the liquid crystal in some directions and has substantially no influence on light traversing the liquid crystal in other directions.
