Abstract

The invention provides a display substrate, a manufacturing method thereof, a display panel and a manufacturing method thereof. The display substrate comprises a flexible substrate and a reinforcing layer positioned on the flexible substrate, the young modulus of the reinforcing layer is greater than that of the flexible substrate, a display area of the display substrate at least comprises first,second and transitional regions, the transitional display region is positioned between the first and second display regions, the reinforcing layer comprises a traditional reinforcing region corresponding to the transitional display region so that the bending elasticity modulus of the transitional display region is lower than those of the first and second display regions. Via the reinforcing layer,the intensity of the display substrate can be improved, the transitional display region can be more adapted to bending or deformation, stress is reduced, and the reliability of the display substrateis improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display substrate and a manufacturing method thereof, a display panel and a manufacturing method thereof. Background technique [0002] In order to reduce the frame width of the display panel, a display panel with edges bent at a large angle, such as about 90 degrees, becomes a feasible option. The shape of the encapsulation cover plate used for such a display panel with a large-angle bending edge needs to be the same. However, it is difficult to make a glass cover plate into a shape bent at a large angle, and other materials, such as resin materials, usually have low strength. The reliability of the display panel is reduced. Contents of the invention [0003] Embodiments of the present invention provide a display substrate and a manufacturing method thereof, a display panel and a manufacturing method thereof, so as to solve the problem of low reliability of a displ...
