要約
(EN)
Provided is a liquid crystal device and in particular, a layered polarization film capable of increasing an angle-of-view of the IPS mode and roll-to-roll bonding a phase difference film and a polarization film. More specifically, the layered polarization film includes: a negative substantially one-axis optical film formed by a thermoplastic polymer having negative molecular polarization ratio anisotropy, a positive optical film formed by a thermoplastic polymer having positive molecular polarization ratio anisotropy, and a polarization film which are layered in this order. A delay axis of the negative substantially one-axis optical film is substantially parallel to a delay axis of the positive optical film, and both axes substantially orthogonally intersect an absorption axis of the polarization film. The main orientation direction of the polymer backbone of the negative substantially one-axis optical film is positioned substantially parallel to the absorption axis of the polarization film. The main orientation direction of the polymer backbone of the positive optical film is positioned substantially vertical to the polarization film.

La présente invention concerne un écran à cristaux liquides et, en particulier, un film de polarisation en couches permettant d'augmenter un angle de vue en mode IPS et un procédé de fixation rouleau sur rouleau d'un film à différence de phase et d'un film de polarisation. Plus précisément, le film de polarisation en couches comprend : un film optique négatif sensiblement monoaxial formé d'un polymère thermoplastique à anisotropie de rapport de polarisation moléculaire négatif, un film optique positif formé d'un polymère thermoplastique à anisotropie de rapport de polarisation moléculaire positif et un film de polarisation, superposés dans cet ordre. Un axe de retard du film optique négatif sensiblement monoaxial est sensiblement parallèle à un axe de retard du film optique positif, et les deux axes croisent de manière sensiblement orthogonale un axe d'absorption du film de polarisation. Le sens d'orientation principal du squelette polymère du film optique négatif sensiblement monoaxial est sensiblement parallèle à l'axe d'absorption du film de polarisation. Le sens d'orientation principal du squelette polymère du film optique positif est sensiblement vertical par rapport au film de polarisation.
