Summary :

A plastics such as polycarbonate take a graded birefringent orientation when a high dc ununiform electric field is applied to its molten phase. This ununiformity is maintained even in a solid phase after decreasing the temperature. Therefore, the plastic plate operating as a variable retardation plate is easily and inexpensively fabricated by using this bulk plastics with graded birefringence.
