Abstract
Official abstract text for this publication.
A flexible organic light emitting display device includes: a display panel configured to output an image; a retardation film formed on an upper portion of the display panel to cover the display panel and formed by laminating a half wave plate and a quarter wave plate; and a polarizing plate attached to the retardation film. A color shift in a black screen can be improved by replacing a barrier film used for face seal with a retardation film including a half wave plate and a quarter wave plate combined at a predetermined angle.
First claim
