ORGANIC ELECTRO-LUMINESENCE DISPLAY PANEL AND MANUFACTUCRING METHOD OF THE SAME

PURPOSE: An organic electroluminescence display panel and a manufacturing method thereof are provided to lower operation voltage by forming a hole transport layer and a hole injection layer in a layer or an electron transport layer and an electron injection layer in a layer. CONSTITUTION: A first electrode connected to a drive thin-film transistor is formed. A bank insulating layer(130) is formed on the first electrode. Bank holes(135) of the bank insulating layer expose the first electrode to the outside. A P-type hole transport layer(134) is formed in the bank holes. A red light emitting layer and a green light emitting layer are formed on the P-type hole transport layer. A hybrid connection layer, a blue light emitting layer, and a second electrode(148) are formed on the front surfaces of the red and green light emitting layers using a vacuum evaporation method.
