Abstract
The present invention discloses a method for fabricating a liquid crystal display (LCD) cell that has improved wide-viewing-angle and devices so made by incorporating the processing steps of first forming a multiplicity of elongated steps on a substrate surface from a negative photoresist layer, then covering the elongated steps with an insulating material such that sloped sidewalls are produced on the multiplicity of elongated steps. After the liquid crystal material is filled into a cavity formed between the substrate and an upper substrate, the liquid crystal molecules are aligned to the same angle as the sloped sidewalls on the multiplicity of the elongated steps such that the viewing angle of the liquid crystal display cell can be improved.
