Problems solved by technology
Due to the poor quality of screen printing and difficult film thickness control
, as shown in Figure 6, the liquid crystal display element produced in the prior art produces the lack of uneven color depth 75 and color lightness 76, resulting in partial uneven display effects in the same screen when the display element is lit.
In the process of screen printing the ground color layer 9, it is easy to produce pinholes 72 and foreign matter 73 to adhere to, and in the module assembly process, the ground color layer 9 located on the outside is prone to scratches 74, so the generated pinholes 72, The lack of foreign objects 73 and scratches 74 will affect its display effect

Embodiment Construction
[0032] The present invention will be further described below in conjunction with drawings and embodiments.
[0033] As shown in Fig. 1 to Fig. 3, the preparation method of cholesteric liquid crystal display element of the present invention comprises the following steps:
[0034] a. Make the upper substrate. Prepare a transparent glass as the upper substrate 1 , firstly clean the upper substrate 1 with lotion, and then make a transparent conductive circuit 11 on one side of the upper substrate 1 . In this embodiment, the conductive circuit 11 is made of transparent conductive material. First, the transparent conductive material of indium tin oxide film is plated on one side of the upper substrate 1, and then the positive photoresist is coated, and then the transparent conductive material is formed on the upper substrate through pre-baking, exposure, curing, development, and etching in sequence. One side of the substrate 1 serves as the conductive circuit 11 . Afterwards, coa...

The invention provides a method for manufacturing a cholesterol LCD element and the manufactured product thereof. The method is that one side of a lower substrate is provided with a blue negative photoresist layer as an undertone layer in the way of knife coating and spin coating, so that film thickness of the undertone layer can be controlled to be uniform without the phenomenon of irregular color or the loss due to pinhole, foreign body and scratches, etc. When the LCD element is lightened, undertone regularity is good.
Description
technical field [0001] The present invention relates to a method for making a cholesteric liquid crystal display element and its finished product, in particular to a method for making a cholesteric liquid crystal display element with a colored negative photoresist as a background color layer and its finished product. Background technique [0002] The general cholesteric liquid crystal display utilizes the characteristics of memory and optical bistable state of cholesteric liquid crystal, so it is especially suitable for display devices that display images with a low update frequency and need to maintain the display image for a long time. Electronic products such as e-books, electronic billboards, and personal digital assistants. And because the cholesteric liquid crystal molecules themselves have optical properties such as optical activity, selective light scattering, and circular polarization dichroism, there is no need to add a polarizing film and a filter plate. In addit...
