<p>Provided is an organic EL display that provides improved visibility in outdoor light. In the present invention, a circular polarizing plate includes a polarizer and an optical laminate that includes a lambda/4 plate (A) and a lambda/2 plate (B). A retardation axis of the optical laminate and an absorption axis of the polarizer intersect at an angle between 35° and 55°. A retardation axis of the lambda/4 plate (A) and a retardation axis of the lambda/2 plate (B) intersect at a right angle, and the lambda/4 plate (A) satisfies formula (I) and the lambda/2 plate (B) satisfies formula (II).(I): Re(450) > Re(550) > Re(630) (II): 0.98 @ Re(450)/Re(550) @ 1.02 where Re(lambda) is the in-plane retardation (nm) for a wavelength lambda nm.</p> |
