Description

technical field [0001] The present invention relates to an organic electroluminescence display panel, in particular to an organic electroluminescence display panel with a moisture and / or oxygen intrusion barrier structure. Background technique [0002] In recent years, flat panel displays are developing toward high brightness, planarization, thinness, and energy saving. In view of this, organic electroluminescent (OEL) display devices have become one of the most promising development directions in the optoelectronic industry. Organic electroluminescent display devices use the self-luminous properties of organic functional materials to achieve display effects. According to the molecular weight of organic functional materials, they can be divided into small molecule organic electroluminescent display devices (smallmolecule OLED, SM-OLED) and polymer light-emitting display (polymer light-emitting display, PLED) two categories. [0003] Organic electroluminescent display device...
