Compared to glass, plastic film is suitable for use in quasi-crystalline display elements, but the plastic film itself is inferior in terms of moisture resistance, heat resistance, optical rotation, liquid crystal resistance, solvent resistance, scratch resistance, etc., and is inferior to other materials. Due to poor adhesion and adhesion with glass substrates, the constituent materials of liquid crystal display elements are often different from those of glass substrate liquid crystal display elements.A cross-sectional view of one example is shown in Figure 1; , 2') is treated with a primer and the primer layer (3') is treated with a primer.
