When the liquid crystal cell assembly 1 is separated, the cloth material 20 is connected to the adjacent one of the substrate regions 111 and 112 along the dividing lines a and c. When the cloth material 20 is formed by screen printing, the printing pattern is simplified and the cloth material 20 is applied using a dispenser. Therefore, it is possible to simplify the control of moving the dispenser to the cloth material application pattern. Thereby further reducing the 10 manufacturing cost.
