Abstract

The embodiment of the invention provides a display panel, a display device and a preparation method of the display panel. The display panel comprises a substrate; a light-emitting element which is arranged on the substrate, wherein the light-emitting element comprises a first connecting end and a second connecting end which are oppositely arranged in the first direction, and an included angle area exists between the side wall of the light-emitting element and the outer surface of the substrate; an electrode element which is arranged on the substrate and comprises a first contact electrode and a second contact electrode, wherein the first contact electrode is connected to the first connecting end, and the second contact electrode is connected to the second connecting end; and an auxiliary insulation part, wherein at least part of the auxiliary insulation part is located between the first contact electrode and the second contact electrode and is arranged in the included angle area. According to the display panel, short circuit caused by mutual connection of the first contact electrode and the second contact electrode due to metal residues can be improved, and the yield of the display panel is effectively improved.

Description

technical field

[0001] The present invention relates to the field of display technology, in particular to a display panel, a display device and a method for preparing the display panel. Background technique

[0002] With the continuous development of display technology, people have higher and higher requirements on the service life and display effect of display devices. The light-emitting device of the Micro Light Emitting Diode Display (Micro LED) display is composed of inorganic materials. Compared with the Organic Light Emitting Diode (OLED) display, it has the advantages of high brightness and long life. Therefore, Micro LED displays are gradually becoming the mainstream displays of current display devices.

[0003] The Micro LED display is to form the Micro LED device on the sapphire or silicon substrate or other substrates, and then transfer the Micro LED device to the thin film transistor (Thin Film Transistor, TFT) array substrate through the transfer method, so tha...
