Abstract

Embodiments of the present invention refer to a display panel, a display device, and a method for manufacturing a display panel, which solve the problems of uneven thickness of pixel units and poor film layer uniformity of pixel units in existing display panels. The display panel includes a pixel defining layer and a conductive layer laminated with the pixel defining layer, a first surface of the conductive layer is provided with a wetting pattern, wherein the first surface is a surface adjacent to the pixel defining layer. In the display panel provided by the embodiment of the present invention, by setting the wetting pattern on the first surface adjacent to the conductive layer and the pixel defining layer, the spreading speed of the ink droplets is accelerated, the concentration difference of the ink droplets is reduced, and the final improvement is achieved. The uniformity of the film layer of the pixel unit is ensured, and the luminous performance of the display device is guaranteed.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display panel, a display device and a method for preparing a display panel. Background technique [0002] Organic light-emitting diode (Organic Light-Emitting Diode, OLED) display devices occupy an important position in the field of display technology due to their many advantages such as thinness, high brightness, low power consumption, and high definition. At present, in the preparation process of OLED display devices, pixel units of OLED display devices are usually prepared based on inkjet printing technology. Specifically, an inkjet printing process is used to inject ink material into the pixel container to form ink droplets, and the ink droplets spread in the pixel container to finally form pixel units. [0003] However, during the spreading process of the ink droplet, the solvent volatilization rate is different between the edge area and the central area of ​​the ink dro...
