| titleOfInvention | Array substrate, preparation method thereof and display panel |
| abstract | The invention relates to the technical field of display, in particular to an array substrate, a preparation method thereof and a display panel. The method is used for solving the problems of coffee ring effect caused by the trapezoidal structure adopted by the pixel defining layer and cathode layer fault caused by the inverted trapezoidal structure adopted by the related technology. An array substrate, comprising: the pixel definition layer divides the substrate into a plurality of sub-pixel areas; the pixel defining layer comprises a first defining layer and a second defining layer which are sequentially stacked from bottom to top, wherein the width of the lower surface of the second defining layer is larger than that of the upper surface of the first defining layer, so that an indentation structure relative to the second defining layer is formed on two sides of the first defining layer along the width direction. The embodiment of the invention is used for manufacturing the OLED display panel by an ink-jet printing technology. |
