    • A display device whose whole packaging effect is good comprises a light-emitting and display layer (10), a planarization layer (20), and a packaging layer (30). At least one circle of closed groove (40) is formed in the planarization layer (20). A projection of the closed circle formed by the groove (40) on a plane where the light-emitting and display layer (10) is completely located beyond the light-emitting and display layer (10) and surrounds the light-emitting and display layer (10). In the display device, by forming a at least one circle of closed groove (40) in the planarization layer (20) to surround the light-emitting and display layer (10), the planarization layer (20) is prevented from continuously extending to the light-emitting and display layer (10) from the boundary of the packaging layer (30), and water and oxygen are prevented from entering the packaging layer (30) through the planarization layer (20), thereby improving the packaging effect of the display device and prolonging the service life of the display device.
