Abstract

The invention provides an organic light emitting display apparatus that has high contrast. The organic light emitting display apparatus includes: a substrate; an organic light emitting device on the substrate to display an image; a sealing member on the organic light emitting device; a semitransparent film on the surface of the sealing member facing away from the organic light emitting device to transmit a portion of external light and to reflect another portion of the external light; a passivation film on the semitransparent film to protect the semitransparent film; and a transmissive black layer between the sealing member and the organic light emitting device to increase contrast, wherein the semitransparent film has a refractive index larger than that of the passivation film.

Description

[0001] Cross references to related patent applications [0002] This application claims the benefit of Korean Patent Application No. 10-2006-0123371 filed in the Korean Intellectual Property Office on December 6, 2006, the entire disclosure of which is incorporated herein by reference. technical field [0003] The invention relates to an organic light-emitting display device, in particular to an organic light-emitting display device with enhanced contrast and impact resistance. Background technique [0004] Recently, display devices have been increasingly replaced by mobile thin flat panel display devices. Among various flat-panel display devices, organic and inorganic organic light-emitting display devices are expected to be the next-generation display device. Organic light-emitting display devices having light-emitting layers composed of organic materials have advantages over inorganic light-emitting display devices, such as high brightness, low driving voltage, short re...
