Abstract

The invention relates to a display device, a display panel and a manufacturing method thereof, and relates to the technical field of display. The display panel comprises a display substrate, a cover plate, a reinforcing layer, a retaining wall and a filling layer. The display substrate is provided with a display region and a peripheral region surrounding the display region. The cover plate and thedisplay substrate are arranged in a mutual covering way. The reinforcing layer is arranged in the peripheral region and is located between the display substrate and the cover plate. The reinforcing layer comprises a plurality of curved first protective corners which are spaced around the display region. The retaining wall is arranged in the peripheral region and is located between the display substrate and the cover plate. The retaining wall has a closed annular structure surrounding the reinforcing layer and is provided with a plurality of curved corners. The inner wall of each corner is correspondingly matched and fit with the outer wall of each first protective corner in a one-to-one way. The filling layer fills in the space formed by the display substrate, the cover plate, the first protective corners and the retaining wall through enclosing and the filling layer is matched and fit with the inner wall of the first protective corners. The display panel can improve the packaging effect and the reliability.

Description

technical field [0001] The present disclosure relates to the field of display technology, and in particular, to a display device, a display panel, and a method for manufacturing the display panel. Background technique [0002] For display panels, encapsulation is an essential process, the purpose is to prevent water vapor and oxygen from corroding the display panel and ensure the display effect, especially for OLED display panels, whose light-emitting devices are easily corroded by water vapor and oxygen. And the glow effect is affected. Currently, there are various packaging methods for display panels, and the more common one is Dam&Fill packaging. However, air bubbles often appear in the corners after the packaging is completed, which affects the packaging effect, and in the process of transportation and use, the corners are prone to cracks, resulting in package failure. [0003] It should be noted that the information disclosed in the above background section is only fo...
