Problems solved by technology

[0006] Since the pixel definition layer 13 or the partition wall 15 is generally made of organic materials, the moisture m (moisture) of the external environment can easily enter the cover plate 19 through the pixel definition layer 13 or the partition wall 15 present in the sealant layer 195 , thereby affecting and destroying the pixels 17 in the luminescence action area 175, forming a phenomenon that the luminescence area in the luminescence action area 175 is reduced, and this situation of reduction in the luminescence action area will seriously affect the luminous intensity and uniformity of light emission in the luminescence action area 175 Of course, it will greatly shorten the service life of OLED 10

Abstract

The invention relates to an organic electroluminescence device, especially an organic electroluminescence device able to prolong service life of pixels in luminous region, mainly provided with a pseudo region between isolation wall / pixel defining layer and sealing gum layer of a cover plate so as to be able to assure the isolation wall or pixel defining layer in the sealing gum layer to prevent water and damp from entering in the cover plate, thus able to effectively prohibit the reduction of luminous area in the luminous region to prolong the service life and luminous quality of pixels in the luminous region.

Description

technical field [0001] The invention relates to an organic electroluminescent device, in particular to an organic electroluminescent device which can prolong the service life and luminous quality of pixels in a luminous action area. Background technique [0002] Organic electroluminescent device (OLED) has the advantages of large viewing angle, low response time, thin display, low power consumption, simple manufacturing process, no need for backlight and can emit full-color light source, so in The new generation of display panels has attracted the attention and use of all parties. [0003] And the organic electroluminescence device of general prior art, such as Figure 1A , Figure 1B and Figure 1C , the OLED 10 is mainly formed with a first electrode 11 on a part of the upper surface of a substrate 105, and an organic light-emitting unit 16 and a second electrode 12 are sequentially formed on the upper surface of the first electrode 11 and other parts of the substrate 10...
