Abstract

The invention provides an organic electroluminescent device and a base plate and cover plate structure thereof. The organic electroluminescent device is provided with a luminous zone and a non-luminous zone around the luminous zone and comprises a base plate, an organic luminous element, a cover plate, sealing glue and filling glue, wherein the organic luminous element is positioned on the base plate and in the luminous zone; the cover plate is positioned on the base plate, and a gap is positioned between the cover plate and the organic luminous element; the sealing glue is positioned betweenthe base plate and the cover plate and in the non-luminous zone; the filing glue is filled in the gap positioned between the cover plate and the organic luminous element; particularly, one of the base plate and the cover plate is provided with a flow passage which extends from a zone inside the sealing glue to a zone outside the sealing glue.

Description

technical field [0001] The present invention relates to an organic electroluminescent device and its substrate and cover plate structure, and in particular to an organic electroluminescent device with a sealant flow channel design and its substrate and cover plate structure. Background technique [0002] The information and communication industry has become the mainstream industry today, especially portable communication and display products are the focus of development. Since the flat panel display is a communication interface between people and information, its development is particularly important. Organic electroluminescent display is a kind of organic electroluminescent device. Because of its advantages of self-luminescence, wide viewing angle, power saving, simple procedure, low cost, wide operating temperature, high response speed and full color, etc., it makes It has great potential, so it is expected to become the mainstream of the next generation of flat panel dis...
