<P>PROBLEM TO BE SOLVED: To provide an organic EL display device excellent in viewing angle characteristics and high in antireflection effect. <P>SOLUTION: An organic EL display device includes a circularly polarizing plate formed by laminating a phase difference film and a polarizing film, the phase difference film being formed of a resin composition (A) including an amorphous polystyrene-based resin and a polyarylene ether resin, satisfying a relation of Re<SB POS="POST">450</SB><Re<SB POS="POST">550</SB><Re<SB POS="POST">650</SB>, and having an Nz coefficient of -0.25 to -0.05 at a wavelength of 550 nm. (Re<SB POS="POST">450</SB>, Re<SB POS="POST">550</SB>and Re<SB POS="POST">650</SB>represent retardations in the in-plane direction of the phase difference film at measurement wavelengths of 450 nm, 550 nm and 650 nm, respectively, the Nz coefficient represents (nx-nz)/(nx-ny), nx represents a refractive index in the phase delay axis direction in the in-plane of the phase difference film, ny represents a refractive index in the phase advance axis direction in the in-plane of the phase difference film, and nz represents a refractive index in the thickness direction of the phase difference film.) <P>COPYRIGHT: (C)2013,JPO&INPIT |
