Kind Code:
A1
Abstract:
A display panel (100), comprising a substrate (10), a first electrode layer (20) provided on the substrate (10), a support structure (103) provided on a pixel defining layer (30), an organic light-emitting layer (50) provided on the first electrode layer (20) and arranged between adjacent pixel defining layers (30), and a second electrode layer (60) provided on the organic light-emitting layer (50) and extended to cover the support structure (103). At least one groove (104) is provided at the side of the support structure (103) facing away from the pixel defining layer (30), and, the width of the groove (104) gradually decreases in the direction from the support structure (103) to the pixel defining layer (30). Also provided are a display device (300) and a manufacturing method for the display panel (100). Damages to the support structure (103) during a manufacturing process of the display panel (100) are reduced, and the reliability of the packaging of the display panel (100) is increased, thus increasing display effects of the display panel (100).
