Abstract:
1. An OLED device comprising in sequence: a transparent substrate having a first surface and a second surface; a light extraction enhancement structure in direct contact with the first or second surface of the substrate; a transparent electrode layer either in direct contact with the first surface of the substrate or the light extraction enhancement structure located on the first side of the substrate; a short reduction layer in direct contact with the transparent electrode layer wherein the short reduction layer is a transparent film having a through-thickness resistivity of 10 an organic light-emitting element disposed over the short reduction layer and including at least one light-emitting layer and a charge injection layer disposed over the light emitting layer; a reflective electrode layer disposed over the charge injection layer wherein the reflective electrode layer includes Ag or Ag alloy containing more than 80% of Ag; and the total device size is larger than 10 times the substrate thickness.
