Abstract

The embodiment of the invention provides a film layer structure and a preparation method thereof, a display panel and a display device, the preparation method of the film layer structure comprises thesteps that a first flat layer is manufactured on one side of a device layer, and the first flat layer is provided with a second protruding middle structure corresponding to a first protruding structure of the device layer; a second flat intermediate structure is manufactured on the side, away from the device layer, of the first flat layer, and the etching speed of the second flat intermediate structure is smaller than that of the first flat layer; the second flat intermediate structure and the second convex intermediate structure are etched to obtain a second flat structure and a second convex structure, and one side, far away from the device layer, of the second convex structure is enabled to be flush with one side, far away from the device layer, of the second flat structure. Accordingto the preparation method of the film layer structure adopted by the embodiment of the invention, the preparation process of film layer planarization can be simplified, an expensive mask plate does not need to be consumed, etching can be comprehensively carried out at the same time, and the cost is greatly reduced.

Description

technical field [0001] The present application relates to the field of display technology, in particular, the present application relates to a film layer structure and a preparation method thereof, a display panel and a display device. Background technique [0002] In the manufacturing process of display products, the film layer structure preparation process involved is very common, and the flatness of the flat layer is often insufficient, which will lead to problems such as low luminous efficiency of the display panel, or color shift, or short lifespan. Contents of the invention [0003] In view of the shortcomings of the existing methods, the present application proposes a film structure and its preparation method, a display panel and a display device to solve the problem of insufficient flatness of the flat layer in the film structure preparation process in the prior art. [0004] In the first aspect, the embodiment of the present application provides a film layer struc...
