Abstract

The invention provides a display panel and a manufacturing method thereof. The display panel comprises a supporting column arranged between a light-emitting layer and a packaging layer; a nesting holeis formed in the supporting column; a part of the material of the packaging layer is embedded into the nesting hole, so that a locking effect is generated on the packaging layer, and therefore, a bonding effect between the packaging layer and the light-emitting layer is improved. The manufacturing method of the display panel comprises the operation of forming a nesting hole in a supporting columnand embedding a packaging layer into the nesting hole; and therefore, the binding force between the packaging layer and the light-emitting layer of the manufactured display panel is high, and the debonding of the packaging layer is effectively prevented.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display panel and a manufacturing method thereof. Background technique [0002] Compared with traditional liquid crystal display (LCD), organic light-emitting diode display (OLED) has the advantages of light weight, wide viewing angle, fast response speed, low temperature resistance, and high luminous efficiency, so it is widely favored in the display technology industry. In addition, the structural characteristics of OLED devices are different from those of LCD devices, so that they have great application potential in the field of flexible and foldable display technology. [0003] An OLED display device has a multi-layer structure, generally including a substrate layer, a thin film transistor array layer, a light-emitting layer and an encapsulation layer, wherein the encapsulation layer is used to seal the components in the display device to isolate the external env...
