Display panel, manufacturing method thereof and display device

Abstract

The embodiment of the invention provides a display panel, a manufacturing method thereof and a display device. The display panel comprises a first electrode layer, a pixel definition layer, a first carrier layer and a light-emitting layer; the pixel definition layer is arranged on the first electrode layer and comprises a body part and a plurality of pixel openings distributed in an array; the first carrier layer is arranged on the pixel definition layer in a stacked mode; the first carrier layer comprises first blocking parts and first current guide parts; all the first blocking parts are located on a peripheral side surrounding at least part of the pixel openings, the first current guide parts are located in the pixel openings, and the transverse resistance of the first blocking parts islarger than that of the first current guide parts; the light-emitting layer is arranged on the first carrier layer in a stacked mode. In the display panel provided by the embodiment of the invention,the transverse resistance of the first blocking parts is greater than that of the first current guide parts, so that current is difficult to flow through the first blocking parts, transverse currentis reduced, the low-gray-scale color cast of a display picture caused by current crosstalk is avoided, and the display effect of the display panel is improved.

Description

technical field [0001] The present invention relates to the technical field of display devices, in particular to a display panel, a method for manufacturing the display panel, and a display device. Background technique [0002] Flat display panels such as Liquid Crystal Display (LCD) panels, Organic Light Emitting Display (OLED) panels, and display panels using Light Emitting Diode (LED) devices have high image quality and low power consumption. , thin body and wide application range, etc., and are widely used in various consumer electronics products such as mobile phones, televisions, personal digital assistants, digital cameras, notebook computers, and desktop computers, and become the mainstream of display devices. [0003] In the display panel, due to the differences in the turn-on voltages of red sub-pixels, green sub-pixels and blue sub-pixels, when a sub-pixel with a high turn-on voltage is turned on, the current flows laterally through the carrier layer, thereby slig...

[0003] In the display panel, due to the differences in the turn-on voltages of red sub-pixels, green sub-pixels and blue sub-pixels, when a sub-pixel with a high turn-on voltage is turned on, the current flows laterally through the carrier layer, thereby slightly lighting up the sub-pixel with a low turn-on voltage. sub-pixels, resulting in low-gray-scale color cast in the display screen and abnormal display
