The invention discloses an organic light-emitting display device based on inkjet printing technology and a manufacturing method thereof. Wherein, the device includes: a substrate and a metal layer, an anode layer, a bank layer, an organic light-emitting layer, and a cathode layer sequentially stacked on the substrate; wherein, an area where the metal layer covers the substrate is set There are three opening areas, exposing the substrate corresponding to the three opening areas; opening a fourth opening area in the area where the dam layer covers the anode layer, exposing the anode layer corresponding to the fourth opening area, the The organic light-emitting layer is disposed in the fourth opening region, wherein a hydrophobic material layer is further disposed on the surface of the dam layer parallel to the substrate. Through the above-mentioned method, the present invention can make the OLED material distribute evenly, so that the OLED device emits uniform light. |
