且つ安価に接着する方法がなかった。<Prior Art> The surface of a liquid crystal display element is generally made of a plastic material such as a polarizing plate, and if it is continued to be used as a display element, the surface will become scratched, impairing its visibility as a display element. Therefore, we placed a replaceable plastic sheet on the front and installed a scratch-resistant glass plate to prevent scratches, but visibility was slightly reduced due to reflections from the surface sheet. . The problem can be solved by bonding a transparent plate such as a glass plate to the liquid crystal display element, but there has been no method for stably and inexpensively bonding the transparent plate at a temperature lower than that which the liquid crystal display element can withstand.
