DISPLAY DEVICE AND MULTILAYERED OPTICAL FILM |
摘要 |
Provided is a display device containing a crystalline piezoelectric polymer layer having a helical chiral polymer (A) that has a weight average molecular weight of from 50,000 to 1,000,000 and has optical activity, an optical compensation layer satisfying the following expression (1), and a linear polarizer. In expression (1), Xc represents a degree of crystallinity (%) of the crystalline piezoelectric polymer layer obtained by a DSC method; MORc represents a standardized molecular orientation of the crystalline piezoelectric polymer layer measured by a microwave transmission molecular orientation meter when a reference thickness is 50 µm; d represents a thickness (µm) of the crystalline piezoelectric polymer layer; and Rth represents a phase difference (nm) in a thickness direction of the optical compensation layer at a wavelength of 550 nm. 0.06 × Xc × MORc × d + Rth ‰¤ 500 |
