Embodiment Construction

[0023] Hereinafter, the present invention will be described more fully with reference to the accompanying drawings showing embodiments of the invention. However, the present invention can be implemented in many different forms and should not be limited to the examples given here. 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. The same reference numerals in the figures denote the same elements.

[0024] It will be understood that when an element such as a layer, film, region, or substrate is referred to as being "on," "connected to" or "coupled to" another element or layer, it can be directly on the other element or layer. layer, or directly connected or coupled to other elements or layers, or intervening elements or layers may also be present. In contrast, when an el...

Abstract

An organic electro-luminescent display device includes barriers in a non-display area to protect a display area from water and oxygen. Barriers may include a permeation prevention barrier, a voltage contact portion, and a blocking layer. A permeation prevention barrier includes contact portions where a barrier layer having a lower permeability than a passivation layer penetrates through the passivation layer. A voltage contact portion penetrates the passivation layer so that a signal supply line contacts a conductive material. A blocking layer covers a wall, a planarization layer, and an inorganic insulation layer, and has a lower permeability than the planarization layer, the wall, and the inorganic insulation layer. The permeation prevention barrier, the voltage contact portion, and theblocking layer may be used in various combinations.

Description

technical field [0001] The present invention relates to organic electroluminescent ("EL") display devices, and more particularly, to organic EL display devices that protect a display area from water and oxygen. Background technique [0002] The organic EL display device is a flat panel display device that displays images by controlling light emission of an organic light emitting layer. In devices such as cellular phones, notebook computers, monitors, and televisions, organic EL display devices are used as image display devices. The organic EL device is a self-luminous type display, and not only has a good contrast ratio, but also has a fast response time. Therefore, the organic EL display device is attracting attention as a next-generation display device. [0003] The active matrix type organic EL display device arranges a plurality of pixels including red (R), green (G) and blue (B) sub-pixels in a matrix arrangement to display images. Each sub-pixel includes an organic ...
