Abstract
A reflective type FFS-LCD includes: a liquid crystal layer; a first substrate formed with counter and pixel electrodes on one side of the liquid crystal layer to generate a fringer field to drive the liquid crystal molecules; a second substrate on the other side of the liquid crystal layer; a first homogeneous alignment layer near the first substrate having a rubbing axis in a selected direction; a second homogeneous alignment layer near the second substrate and having a rubbing axis in a selected direction; a polarizer having a selected polarizing axis; and a reflective plate. Retardation occurs in the liquid crystal layer by (2n+1)&lgr;/4 when the liquid crystal molecules in the liquid crystal layer are driven by the fringe field.
