The embodiment of the invention provides a display panel and a manufacturing method of the display panel, an isolation column used for disconnecting a light-emitting layer is arranged at the edge of atransition region, and a sunken notch is designed in the side surface of the isolation column, so that the light-emitting layer can be disconnected at the isolation column during subsequent manufacturing of the light-emitting layer. Meanwhile, the middle layer below the isolation column comprises a reflecting layer with the uneven surface; when photoresist is removed through an exposure process in the manufacturing process of the display panel, the photoresist remaining at the notch is effectively removed by diffusing exposure light to the notch, so that the packaging reliability of the isolation column and even the transition area is guaranteed. The barrier capacity to oxygen and water vapor is further enhanced, and the oxygen and the water vapor are more effectively prevented from penetrating through the isolation column from the transition area to permeate into the display area.
Description
technical field [0001] The invention belongs to the field of display technology, and in particular relates to a display panel and a manufacturing method of the display panel. Background technique [0002] With the rapid development and progress of display technology, users' demand for large screen-to-body ratio of display devices is also increasing. In order to solve the functions of display devices such as front cameras and optical sensors, many screen manufacturers choose to open holes in the display screen for Holds functional components such as cameras and other sensors. However, if a hole is made on the screen, when making the spacer around the hole, photoresist involved in other processes may remain in the gap of the spacer, so that the display panel may face oxygen and water vapor penetration and reliable packaging. Sexual decline and other issues. Contents of the invention [0003] In order to improve the above technical problems, the present invention provides a...
