ABSTRACT:
A liquid crystal cell for use in a display and a method for manufacturing such display is disclosed. Each cell of such display includes a membrane which is manufactured by conventional semiconductor processing technology. Such membrane has semiconductor structural support members between which liquid crystal fluid is retained. Such membrane and residual liquid crystal fluid in the cell have substantially the same thermal coefficient of expansion as a silicon integrated circuit chip attached to the rib members. The membrane prevents warpage and deterioration of each liquid crystal cell, maintains uniformity of spacing between structural members of the cell, and enables a high quality cell to be fabricated with accompanying improved cell fabrication yield.
