Abstract

The invention relates to the technical field of display, and discloses a display panel, a preparation method thereof and a display device. The display panel comprises: a substrate having a first surface and a second surface opposite to each other; the first pixel limiting layer comprises a plurality of first pixel limiting strips, the first pixel limiting strips are arranged on the first face in the first direction, and a gap is formed between every two adjacent first pixel limiting strips; the second pixel limiting layer comprises a plurality of second pixel limiting strips, the second pixel limiting strips are arranged on the first face in the second direction and span the first pixel limiting layer, the first direction intersects with the second direction, each second pixel limiting strip is provided with a third face, a fourth face and a fifth face, the third face is the face close to the substrate, the fourth surface is a side surface which is far away from the substrate, the fifth surface is a side surface which is connected between the third surface and the fourth surface, the fifth surface extends along the second direction, and a plurality of protruding parts are arranged on the fifth surface. The display panel can improve the ink utilization rate of the light-emitting layer.

Description

technical field [0001] The present disclosure relates to the field of display technology, in particular, to a display panel, a method for preparing the display panel, and a display device including the display panel. Background technique [0002] Compared with Liquid Crystal Display (LCD), Organic Light-Emitting Diode (OLED) has the advantages of self-luminescence, fast response, wide viewing angle, high brightness, bright color, light and thin, etc., and is considered to be the next generation display technology. OLED film-forming methods mainly include evaporation process and solution process. The evaporation process is relatively mature in the application of small-sized display panels, and the technology has been applied in mass production at present. The OLED film-forming methods of the solution process mainly include inkjet printing, nozzle coating, spin coating, screen printing, etc. Among them, inkjet printing technology is considered as a large-size An important w...
