A liquid crystal cell comprises two substrates coated with respective alignment layers (polyimide layers). The upper substrate is coated with the polyimide layer but without the orientation process (rubbing process). The lower substrate coated with polyimide layer and rubbed is made by a method including the steps of a first rubbing process on the coated polyimide layer on the substrate, coating the rubbed polyimide layer with a photoresist layer, removing part of the photoresist layer to expose a portion of the rubbed polyimide layer, carrying out a second rubbing process, and then removing the remainder of the photoresist layer. The lower oriented (rubbed) substrate and the upper non-oriented (non-rubbed) substrate are then assembled together to form the liquid crystal cell to improve the scope of the viewing angle and the gray-level order problem.
