Document Type and Number:
Japanese Patent JP5976759
Kind Code:
B2
Abstract:
Disclosed is an organic light emitting display (OLED) apparatus that includes a substrate; an organic light emitting element on the substrate, the organic light emitting element including a first electrode, an organic light emitting layer and a second electrode; a viscoelastic layer on the organic light emitting element, wherein an elastic portion of the viscoelastic layer is about 30% or more, the elastic portion being defined by : Elastic portion (Ep) (%) = (Ã/à 0 ) × 100, wherein à 0 is an initial stress generated when a strain of about 50% is applied to the viscoelastic layer and à is a final stress measured after the strain is continuously applied thereto for about 180 seconds, with the initial stress à 0 and the final stress à being measured at about 80°C through a relaxation modulus test.
