Abstract

The invention discloses an organic electroluminescence device and a display panel. The organic electroluminescent device includes: an organic functional layer; the organic functional layer includes a first pixel area, a second pixel area and a third pixel area; the organic functional layer in the first pixel area includes a first electron blocking layer and a first The light-emitting layer, the organic functional layer in the second pixel area includes a first electron blocking layer, the first light-emitting layer, the second electron blocking layer and the second light-emitting layer, and the organic functional layer in the third pixel area includes the first electron blocking layer , the first light-emitting layer, the second electron blocking layer, the second light-emitting layer, the third electron blocking layer and the third light-emitting layer, thereby reducing the defective rate of the organic electroluminescent device.

Description

technical field [0001] The invention relates to the technical field of display panels, in particular to an organic electroluminescent device and a display panel. Background technique [0002] Organic light-emitting diodes (OLEDs) are becoming a new generation of display devices gradually replacing liquid crystal displays (LCDs) due to their advantages such as self-luminescence, wide color gamut, fast response, high contrast, low power consumption, and simple manufacturing process. In recent years, with the application of organic electroluminescent diodes in televisions, mobile phones and other products, the research and production of organic electroluminescent diodes has become a hot spot in the optoelectronic industry. [0003] An organic electroluminescent diode is an organic material that is coated on a thin-film transistor (TFT) array substrate to form a single light emission. By controlling the TFT switch, the purpose of controlling the individual light emission of sub-...
