示不良を起こし、従来の固定方法は使用できなかった。<Problems to be Solved by the Invention> However, in the conventional fixing method, distortion of the substrate, frame, and rubber is transmitted to the liquid crystal panel, resulting in a decrease in display quality and display defects of the liquid crystal panel. In particular, in liquid crystal panels using ferroelectric liquid crystal, the thickness of the liquid crystal layer is extremely thin at 1 to 2 μm, and
The orientation of the liquid crystal was also very poor, and even the slightest distortion caused display defects, making conventional fixing methods unusable.
