Embodiment Construction
[0055] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0056] An embodiment of the present invention provides a method for manufacturing a display substrate, such as figure 1 As shown, the method may include:
[0057] Step 101 , forming a first flat layer on the base substrate on which the film layer before the flat layer is formed.
[0058] The first planarization layer 130 may be formed on the base substrate 120 formed with the pre-planarization layer film layer 110 . The schematic diagram of the base substrate 120 formed with the first flat layer 130 can refer to figure 2 . For example, the thickness of the first flat layer 130 may be 2 μm (micrometer), and the material forming the first flat layer 130 may be a resin material.
[0059] In the embodiment of the present invention, wh...

Abstract
The present invention disclosed a manufacturing method, display substrate and display device for display substrates, which belong to the field of display technology.The manufacturing method of this display substrate includes: forming the first flat layer on the substrate substrate with a flat layer of the front membrane; forming the first buffer layer on the side of the first flat layer away from the side of the substrate substrate; on the first buffer layerFar away from the side of the substrate substrate to form a second buffer layer; form a wire grid polarizer WGP on the side of the second buffer away from the side of the substrate substrate.The present invention improves the flat performance of the first flat layer.The invention is used to display the manufacturing of the substrate.
Description
technical field [0001] The invention relates to the field of display technology, in particular to a method for manufacturing a display substrate, a display substrate and a display device. Background technique [0002] At present, in the manufacturing process of the liquid crystal display device, a wire grid polarizer (WGP) is usually used to replace the polarizer disposed on the traditional display substrate, so as to realize the ultra-thinning of the liquid crystal display device. [0003] In the related art, the manufacturing process of the display substrate in the liquid crystal display device includes: firstly, forming a flat layer on the base substrate on which the front film layer of the flat layer is formed, and forming a buffer layer on the side of the flat layer away from the base substrate. Afterwards, a WGP is formed on the side of the buffer layer away from the base substrate. [0004] However, during the process of forming the WGP, the material of the buffer la...
