Abstract

The invention relates to a display panel, a display panel manufacturing method and a display device. The display panel comprises a deformation layer; the deformation layer is a material layer formed by a material which can expand and deform and can restore to the original shape, the deformation layer is clamped between a pixel definition layer and a hole injection layer of the display panel; the deformation layer is used for disconnecting the hole injection layer of the display panel and a hole transmission layer in the manufacturing process of the display panel. The hole injection layer and the hole transmission layer are disconnected by utilizing the deformation layer in the manufacturing process of the display panel, so that hole transverse flowing is prevented to form transverse leakage current, the pixel light-emitting purity is improved, and the display effect is improved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display panel, a method for manufacturing a display panel, and a display device. Background technique [0002] OLED (Organic Light-Emitting Diode, Organic Light-Emitting Diode) panel has many advantages such as thinness and low power consumption, and has gradually become the current mainstream display technology. Usually, an OLED panel includes an anode layer, a hole injection layer, a hole transport layer, and a light-emitting layer. , electron transport layer, electron injection layer, cathode layer. [0003] The working principle of the OLED panel is that the anode layer emits holes under the action of an electric field, the holes pass through the hole injection layer, the hole transport layer is transported to the light-emitting layer, the cathode layer emits electrons under the action of the electric field, and the electrons pass through the electron injection l...
