Abstract

An improved organic electroluminescent device is provided. The device may include a protection layer provided on non-light-emitting regions of a panel to prevent reflection of external light. The protection layer may include an optical filter used in combination with a black insulator. The protection layer may provide for improved reflectance and transmissivity, and improved brightness without a commensurate reduction in contrast.
