Title: (EN) ORGANIC EL DISPLAY DEVICE
Abstract: front page image
(EN)

Disclosed herein is an organic EL display device including: a base resin substrate layer (10); an organic EL element layer (20) provided on the base resin substrate layer (10); an underlayer (29) provided on the organic EL element layer (20); and a hard coat layer (30) provided on the underlayer (29). A difference between a Martens hardness of the hard coat layer (30) alone and a weighted average Martens hardness of components of a stack layer by stress dispersion coefficients of the components is less than or equal to 79 N/mm2. The stack layer includes the base resin substrate layer, the organic EL element layer, and the underlayer.
