Display panel, manufacturing method of display panel and display device

Abstract

The embodiment of the invention provides a display panel, a manufacturing method of the display panel and a display device. The display panel comprises a substrate; a functional layer at least comprises an opening layer and a pixel definition layer located on the side, away from the substrate, of the opening layer, the pixel definition layer comprises a body part and a pixel opening penetrating through the body part, and isolation through holes are formed in the functional layer in a penetrating mode; each isolation through hole comprises a first isolation opening located in the opening layer, a second isolation opening located in the side, away from the substrate, of the first isolation opening and a first communication opening communicating the first isolation opening with the second isolation opening, and the first orthographic projection of the first isolation opening on the substrate and the orthographic projection of the pixel opening on the substrate are arranged in a staggered mode; the size of the first orthographic projection is larger than that of the orthographic projection of the first communication port on the substrate, and an isolation gap staggered with the first communication port is formed in the first isolation opening. The display panel can improve low-gray-scale color cast, caused by current crosstalk, of a display picture, 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, and 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 power saving. It is widely used in various consumer electronic products such as mobile phones, TVs, personal digital assistants, digital cameras, notebook computers, desktop computers, etc., and has become the mainstream of display devices. [0003] In the display panel, due to the difference in turn-on voltage of red sub-pixels, green sub-pixels and blue sub-pixels, when the sub-pixels with high turn-on voltage are turned on, the current flows laterally through the carrier layer, so that the turn-on voltage is slightly low. sub-pixels, resulting in ...

Problems solved by technology

[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
