Problems solved by technology

[0017] However, since the above-mentioned organic EL display device includes two stacked organic EL display devices, the thickness and cost of the device increase accordingly, and an additional driving device is required.
Moreover, since two organic EL devices are overlapped, it is not easy to install a getter for protecting the organic layer 32.

Abstract

An organic electroluminescence (EL) display device having a portion emitting light toward a side of a substrate and a portion emitting light toward another side of the substrate. The organic EL display device includes a substrate, a first organic light emitting unit formed on the substrate, and a second organic light emitting unit formed on the substrate and adjacent to the first organic light emitting unit. The first organic light emitting unit and the second organic light emitting unit emit light in different directions.

Description

Technical field [0001] The present invention relates to an organic electroluminescence (EL) display device, which has an area that emits light toward a substrate and an area that emits light away from the substrate, and particularly relates to a first organic light emitting unit that emits light away from the substrate and a light emitting unit that emits light toward the substrate. Organic EL display device of the second organic light emitting unit. Background technique [0002] Cross reference of related applications [0003] This application claims the priority and benefits of Korean Patent Application No. 10-2004-0036636 filed on May 22, 2004, and its entire contents are incorporated herein by reference. [0004] Generally, an organic EL display device is a self-luminous device that electrically excites a fluorescent organic compound to emit light. As a next-generation display device, it can be driven by low voltage, it is thin and has a wide viewing angle and fast response spe...
