Abstract

The invention relates to a display panel, a manufacturing method thereof and a display device. The display panel comprises a substrate, an isolation column, a passivation layer and a display layer, wherein the substrate comprises an opening area, a transition area surrounding the opening area and a display area surrounding the transition area; the isolation column is arranged in the transition area, and the side wall of the isolation column is sunken inwards to form a sunken part; the passivation layer at least covers the isolation column and covers the isolation column in a conformal manner,and the passivation layer covers the sunken part; the display layer covers the transition area and the display area and comprises a light-emitting layer, and the light-emitting layer is discontinuously arranged in the sunken part of the isolation column. According to the display panel provided by the invention, the effectiveness of the isolation column for cutting off the water-oxygen invasion channel can be ensured, and the packaging yield of the display panel is improved.

Description

technical field [0001] The present disclosure relates to the field of display technology, and in particular, to a display panel, a manufacturing method thereof, and a display device. Background technique [0002] With the increasing user requirements for products and the fierce competition in the industry, most mobile phone manufacturers are pursuing a higher screen-to-screen ratio in order to bring more dazzling visual impact to users and win market competition. However, for the camera and some sensors, it restricts the development of the screen to a higher screen-to-body ratio. Putting the camera and some sensors in the screen is attracting great attention in the industry. [0003] When some sensors such as a camera are placed in the screen, holes need to be made on the screen, and opening holes on the screen can easily make the common luminescent material layer form a water and oxygen intrusion channel. At present, the blocking effect on the common luminescent material l...
