Abstract

The present invention relates to a liquid crystal alignment structure of a twisted nematic liquid crystal display (TN-LCD), in which the alignment directions of two liquid crystal alignment films are 90 degrees and 180 degrees such that the display screen of the TN-LCD can be upwardly extended along the 90-degree and 180-degree directions. By incorporating the LCD alignment film with a polarizer structure, the present display screen of the TN-LCD of the present invention can be enlarged within viewing-angle range to attain its optimized viewable screen.
