Embodiment Construction

[0033] The present invention will now be specifically described in conjunction with preferred embodiments with reference to the accompanying drawings. Like reference characters designate corresponding parts throughout the several figures. However, this invention may be embodied in different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough, and will fully convey the scope of the invention to those skilled in the art. In the drawings, the size and relative sizes of layers and regions may be exaggerated for clarity.

[0034] It will be understood that when an element such as a layer, film, region or substrate is referred to as being "on" another element, it can be directly on the other element or intervening layers may also be present. In contrast, when an element is referred to as being "directly on" another element, there are no intervening elements present.

Abstract

The present invention relates to a both-side light emitting organic EL display device including a reflection film having an opening and a first electrode formed on the reflection film and in the opening. An organic layer is formed on the first electrode, and a second electrode is formed on the organic layer. The opening corresponds to a central portion of the first electrode.

Description

[0001] Cross References to Related Applications [0002] This application claims priority and the benefit of Korean Patent Application No. 10-2004-0091561 filed on November 10, 2004, which is hereby incorporated by reference as if set forth in its entirety. technical field [0003] The present invention relates to a double-sided light-emitting organic electroluminescent display device, and more specifically, to a double-sided light-emitting organic electroluminescent display device including a reflective film arranged under a first electrode. Background technique [0004] In general, an organic electroluminescence (EL) display device is a self-luminous flat panel display device that emits light by electrically exciting an organic compound. The organic EL display device can be manufactured at low temperature, it has a high response speed of 1 ms or less, it has low power consumption, it has a wide viewing angle due to its self-luminous properties, and it has a high contrast r...
