Abstract

The embodiment of the invention provides a display panel, a display device and a preparation method of the display panel, and aims to reduce the production process deviation of the display panel. Thedisplay panel comprises a first substrate and a second substrate which are oppositely arranged, a plurality of light-emitting units which are located on the side, facing the second substrate, of the first substrate and comprise display units and marking units; the second substrate is provided with a positioning mark, and the marking unit and the positioning mark are arranged in an aligned mode. Inthe embodiment of the invention, the process error of the display panel can be reduced by reusing the light-emitting unit as the marking unit.

Description

technical field [0001] The present invention relates to the technical field of display devices, 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, a Micro Light Emitting Diode (Micro-LED) display device has become an indispensable display device type. A micro light-emitting diode is a device with a size ranging from a few microns to hundreds of microns. Because it is much smaller than ordinary light-emitting diodes, it is possible for a single micro LED to be used as a pixel for display. A Micro LED display is a display that uses a high-density Micro LED array as a display pixel array to display images. [0003] At present, Micro LED displays mainly include two parts: a light-emitting substrate and a color filter substrate. The Micro LEDs are aligned on the light-emitting substrate, and the color filter substrate is provided with color resists ...
