| titleOfInvention | Display backplane, display device and manufacturing method |
| abstract | Embodiments of the present application provide a display backplane, a display device, and a manufacturing method. The display backplane includes a base substrate and a pixel defining layer disposed on one side of the base substrate. The pixel defining layer includes a communication area and a middle part, and the communication area is It is used for inkjet printing of the connected area of the organic light-emitting layer. The pixel defining layer includes edge parts located on both sides of the connected direction of the connected area; the middle part is made of a lyophilic material and extends in the same direction as the edge part in the connected area; the edge part The height relative to the base substrate is greater than the height of the middle portion relative to the base substrate. When inkjet printing is carried out on the above-mentioned display backplane, the Unicom area can make the ink communicate in the length direction of the Unicom area; and because the middle part is made of a lyophilic material and is lower than the edge; when the ink is printed to the middle part , the ink will flow from the middle part to the area between the middle part and the edge part, so that the ink will communicate in the width direction of the communication area, thereby improving the uniformity of the long and short axes of the pixel unit after film formation. |
