Embodiment Construction
[0033] In order to understand the purpose, features and advantages of the present invention more clearly, the present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0034] See Figure 2a ~ 2g It is a structural schematic diagram of an embodiment of the present invention.
[0035] Such as Figure 2a As shown: a PI alignment film 21 (which may be polypropylene resin or polyimide resin) is printed on the surface of the TFT array substrate 20 to form an alignment film for controlling the alignment of liquid crystal molecules.
[0036] Such as Figure 2b As shown: a thickness-controlled frame glue wall 22 (which can be heat-curable epoxy resin or ultraviolet-curable epoxy resin) is coated at a certain height on the periphery of the array substrate 20 where the alignment film is formed. The scattered spacers are used to control the thickness of the liquid crystal layer (not shown), so that a uniform gap is formed between...
