Display panel and display device
By introducing a first inorganic layer with a low elastic modulus into the encapsulation layer of the display panel and adjusting its ratio and density difference with the second inorganic layer, the problem of interface peeling of the display panel under external force is solved, the encapsulation stability and water and oxygen barrier capability are improved, and the risk of encapsulation failure is reduced.

AI Technical Summary
Existing organic light-emitting diode (OLED) display panels are prone to deformation under external force, which can cause the interface between the light-emitting functional layer and the thin-film encapsulation layer to peel off, resulting in cracks, increasing the risk of moisture intrusion, and leading to encapsulation failure.
A first inorganic layer with a low elastic modulus is introduced into the encapsulation layer of the display panel and placed close to the light-emitting functional layer. By adjusting the ratio of the elastic modulus of the first inorganic layer to that of the second inorganic layer to between 0.6 and 0.9, and combining the differences in thickness and density, the interfacial tangential stress is reduced, and interfacial delamination is avoided.
It effectively reduces the risk of display panel encapsulation failure, improves interface stability and water and oxygen barrier performance, and reduces film peeling and cracking.
