Abstract

The embodiment of the invention provides a display panel and a preparation method of the display panel. The display panel comprises an array substrate, a pixel definition layer and a first carrier layer; the pixel definition layer is located on the array substrate; the pixel definition layer comprises a plurality of pixel openings distributed in an array mode; the pixel openings comprise a first opening close to one side of the array substrate and a second opening far away from one side of the array substrate; the first carrier layer is arranged on the side, deviating from the array substrate,of the pixel definition layer; a plurality of breaking parts are arranged on the first carrier layer; the minimum distance between the orthographic projection of the breaking parts on the array substrate and the orthographic projection of the first openings on the array substrate is a first distance L1, and meets the following condition that: L1 is larger than 0 and smaller than or equal to 2 microns. According to the display panel and the preparation method of the display panel of the invention, a conductive path between at least part of adjacent light-emitting elements can be blocked, and the display effect of the display panel is improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display panel and a method for preparing the display panel. Background technique [0002] Organic light emitting diode (Organic Light Emitting Diode, OLED) display device is a kind of active light emitting display device, because of its advantages such as simple manufacturing process, low cost, high contrast, wide viewing angle, low power consumption, etc., it has become the mainstream flat panel display technology. . [0003] Multiple light-emitting elements of an OLED display device often have a common carrier layer, that is, the common carrier layer is connected to multiple light-emitting elements. When a light-emitting element is in a light-emitting state, the driving current applied to the light-emitting element can be applied to adjacent light-emitting elements along the common carrier layer to a certain extent, so that the light-emitting element that should be in a non...
