Abstract

Provided are an organic light emitting display device and a method for manufacturing the same. The organic light emitting display device includes a substrate, first electrode positioned on the substrate, a pixel defining film positioned on the substrate and at least partially exposing the first electrode, an organic layer positioned on the first electrode and having a central portion and an edge portion, and a cover film at least partially overlapping the edge portion of the organic layer.

Description

technical field [0001] The present invention relates to an organic light emitting display device and a method for manufacturing the organic light emitting display device. More particularly, the present invention relates to an organic light emitting display device including an electrode and an organic layer formed on the electrode and a method of manufacturing the organic light emitting display device. Background technique [0002] Displays that realize various information on a screen are core technologies in the information-oriented communication era, and are progressing towards slimness, light weight, portability, and high performance. Accordingly, a flat panel display including an organic light emitting display device, which can overcome disadvantages of a conventional cathode ray tube (CRT) which is heavy in weight and large in size, has drawn increasing attention. [0003] Here, the organic light emitting display device is a self-luminous device using a thin organic lig...
