titleOfInvention | Organic EL display device |
abstract | The object of the present invention is to prevent the precipitation of the additive of the λ / 4 retardation film and to suppress the environmental fluctuation of the retardation value, the image is high-definition, the image quality is deteriorated, the hue is deteriorated with time and the light. An organic EL display device in which a decrease in extraction efficiency is suppressed is provided. The organic EL display device of the present invention includes a light emitting element and a circularly polarizing plate disposed on a surface on the viewing side of the light emitting element. The circularly polarizing plate includes a polarizer, the polarizer, and the light emitting element. A λ / 4 retardation film and a protective film which is disposed on the viewing side of the polarizer and has an ultraviolet absorption performance. The λ / 4 retardation film has an acetyl group substitution degree X Containing a cellulose ester satisfying the following formula (1), a compound (A) represented by the following formula, an ultraviolet absorber having an OH group, and a retardation increasing agent, Formula (1) 2.7 <= X <= 3.0 The λ / 4 retardation film satisfies the following formula (2), where Ro is a retardation value in the in-plane direction with respect to light having a wavelength of 550 nm, and Rth is a retardation value in the thickness direction. Formula (2) 100 ≦ Ro ≦ 170 nm 0 ≦ Rth ≦ 300nm [Chemical 1] |
