Abstract
A display panel and a manufacturing method thereof are provided. The display panel includes a buffer layer and/or at least one adhesive layer. The buffer layer is disposed on a bottom of the display panel, and the adhesive layer is disposed between two of adjacent layers in a layered structure of the display panel. Wherein, the buffer layer and the adhesive layer have materials having Poisson's ratio of less than 0.1.
Claims10
A display panel, comprising:
- a flexible substrate layer;
- a display layer disposed on the flexible substrate layer;
- a touch control layer disposed on one surface of the display layer away from the flexible substrate layer;
- a polarizer disposed on one surface of the touch control layer away from the display layer;
- a cover plate disposed on one surface of the polarizer away from the touch control layer;
- a buffer layer disposed on one surface of the flexible substrate layer away from the display layer, wherein the buffer layer has a material having Poisson's ratio of less than 0.1;
- and
- at least one adhesive layer disposed between two of adjacent layers in a layered structure of the display panel, wherein the adhesive layer has another material having Poisson's ratio of less than 0.1.
