Abstract

The invention relates to an organic electroluminescence component and a manufacturing method thereof. The organic electroluminescence component comprises a basal plate, wherein a first electrode, an organic material layer, a second electrode and a sealing layer are sequentially formed on the basal plate, the first electrode is used as an anode, and the second electrode is used as a cathode and is a composite transparent structure layer for realizing the light emitting at the top. By forming the composite transparent cathode emitting light at the top, the invention enables the organic electroluminescence component to emit the light from the top and enhances the light-emitting utilization rate and the light transmission rate effectively, which not only enhances the aperture opening ratio of a display screen but also can obtain better display effect. Meanwhile, by adding a netty confluence layer on a semitransparent metal layer with high resistance, the invention ensures high transmissivity, also enhances the conducting power of current, meets the requirement of a top transmission type organic electroluminescence component effectively and can be applied to a display device with double-face display. The invention has simple and reliable structure and preparation process and extensive application prospect.

Description

technical field [0001] The invention relates to a flat panel display device and a manufacturing method thereof, in particular to an organic electroluminescence device and a manufacturing method thereof. Background technique [0002] Organic Light Emitting Diode (OLED) is a new type of flat panel display device, which has many advantages such as active light emission, high brightness, ultra-thin, low power consumption, large viewing angle and wide operating temperature range. [0003] The organic electroluminescent device is a multilayer thin film superimposed structure. Several layers of organic material layers are sandwiched between a pair of electrodes. When an appropriate voltage is applied, electrons and holes are injected from the corresponding electrodes into the organic material layer. Meet and recombine at the corresponding position in the transmission, release energy and emit light. Since the total thickness of the laminated multilayer thin film structure is usuall...
