Embodiment Construction

[0018] Please refer to figure 2 , Which is a schematic structural view of the first embodiment of the organic electroluminescence display device of the present invention. The organic electroluminescence display device 2 includes a transparent substrate 20, a first electrode 22, an organic layer 23 and a second electrode 21 arranged on the surface of the transparent substrate 20 in sequence. The organic layer 23 includes a three-layer structure of a hole transport layer 232, an organic light-emitting layer 230, and an electron transport layer 231 sequentially disposed on the surface of the first electrode 22. The second electrode 21 includes a conductive light-transmitting layer 210, a conductive light-absorbing layer 211 and a metal layer 212 sequentially disposed on the surface of the organic layer 23.

[0019] Wherein, the first electrode 22 is an anode, which is a transparent material, such as indium tin oxide (ITO) or indium zinc oxide (IZO), and its thickness is 25-100 nm. T...

Abstract

The present invention provides an organic electroluminescent display device and a method for manufacturing the same. The organic electroluminescent display device comprises a transparent substrate, and a first electrode, an organic layer and a second electrode which are arranged on the surface of the transparent substrate in turn, wherein, the second electrode comprises a conductive euphotic layer, a conductive light- absorption layer and a metal layer which are arranged on the surface of the organic layer in turn.

Description

Technical field [0001] The invention relates to an organic electroluminescence display device and a manufacturing method of the organic electroluminescence display device. Background technique [0002] With the rapid development of science and technology, people’s requirements for display devices are increasing day by day, making display devices lighter, thinner, and more power-saving. As a result, Organic Light Emitting Display (OLED) ). Compared with liquid crystal display (LCD), organic electroluminescent display is a self-luminous display, and does not require a backlight module with high energy consumption, so it can be lighter, thinner, and more power-saving. [0003] According to the different organic film materials used, organic electroluminescence display devices can be divided into small molecule electroluminescence display devices and polymer light emission display devices (Polymer Light Emitting Display, PLED). [0004] The basic structure of an organic electrolumines...
