Preparation of the Ethylene-Vinyl Acetate Copolymer
[0064]An ethylene-vinyl acetate copolymer was prepared in this example, wherein the mass percent of the vinyl acetate monomeric unit in the copolymer was 20% and the number average molecular weight of the ethylene-vinyl acetate copolymer was 50,000.
[0065]It should be understood that the preparation method of the above ethylene-vinyl acetate copolymer belongs to the prior art which will not be described in detail herein.
[0066]After the small-molecular substances were removed with solvent, the ethylene-vinyl acetate copolymer was observed by a scanning electron microscope. It can be seen from FIG. 1 that the ethylene-vinyl acetate copolymers formed a network structure and had sheet shape in the microscopic morphology, which allowed small-molecular substances (e.g. the liquid crystal molecules) to be anchored in the meshes of the network structure and to be induced to orientate in accordance with the arrangement of the ethylene-vinyl a...

Preparation of the Liquid Crystal Film Layer and the Display Panel
[0067]A liquid crystal film layer was prepared in this example, which comprised the ethylene-vinyl acetate copolymers as prepared in example 1 and liquid crystal molecules dispersed in the meshes of the network formed by the ethylene-vinyl acetate copolymers.
[0068]Wherein, the mass percent of the ethylene-vinyl acetate copolymers based on the liquid crystal film layer was 20%, the thickness of the liquid crystal film layer was 2 μm, the liquid crystal molecules were SLC1717 (available from Chengzhi Yonghua Liquid Crytal Materials Co., Ltd.) and the mass percent of which was 80% based on the liquid crystal film layer.
[0069]The liquid crystal molecules SLC1717 and the ethylene-vinyl acetate copolymers prepared in example 1 were mixed vigorously to uniform at room temperature at the above ratio (the mixing ratio of the liquid crystal molecules to the ethylene-vinyl acetate copolymers was 80:20 by mass) so as to obtain a ...

Preparation of the Ethylene-Vinyl Acetate Copolymer
[0073]In this example, an ethylene-vinyl acetate copolymer was prepared in the same way with that of example 1 except that, the mass percent of the vinyl acetate monomeric unit in the copolymer was 35% and the number average molecular weight of the ethylene-vinyl acetate copolymer was 10,000.
[0074]It should be understood that, the preparation method of the above ethylene-vinyl acetate copolymer belongs to the prior art which will not be described in detail herein.
[0075]After the small-molecular substances were removed with solvent, the ethylene-vinyl acetate copolymer was observed by a scanning electron microscope. The result was the same as shown in FIG. 1, wherein the ethylene-vinyl acetate copolymers formed a network structure and had sheet shape in the microscopic morphology, which allowed small-molecular substances (e.g. the liquid crystal molecules) to be anchored in the meshes of the network structure and to be induced to ori...
