Abstract

The embodiment of the invention relates to a film layer structure, a display panel, a display device and a preparation method of the film layer structure, and solves the problems of uneven thickness and poor film layer uniformity of pixel units borne in the existing film layer structure. The film layer structure comprises a pixel defining layer and a conductive layer which is arranged in a laminated mode with the pixel defining layer, the first surface of the conductive layer comprises a protruding part, and the first surface is adjacent to the pixel limiting layer. According to the film layerstructure provided by the embodiment of the invention, the purpose of preparing the pixel unit with uniform thickness and good film layer uniformity based on the surface tension of ink droplets is achieved by means of arranging the protruding part on the first surface, which is adjacent to the pixel defining layer, of the conductive layer, the film layer uniformity of the pixel unit is improved,and the light emitting performance of the film layer structure is guaranteed.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a film layer structure, a display panel, a display device and a method for preparing the film layer structure. Background technique [0002] OLED (Organic Light-Emitting Diode) display device occupies an important position in the field of display technology due to its advantages of 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 droplet, whi...
