We have succeeded in the development of a new front surface film, it has the function of improving the viewing‐angle properties (especially, improvement of gray scale inversion in downside direction) of TN‐mode TFT‐LCDs, in addition to the conventional function of the protection of polarizer and the glare prevention under bright room surrounding). The excellent viewing‐angle properties have been realized in combing this new front surface film with the optical compensation film for TN‐mode (Wide‐View Film, for short WV Film). According to the proposal of this method, it has been expected to apply TN‐mode to large‐Size LCD monitors and LCD TVs hereafter.
