Recently, the liquid crystal display-panel is commonly used for the monitor devices in various electronics machines and household appliances. This in turn increased the amount of liquid crystal display-panels wasted from the display making company and electronic scraps. It is important to recycle them, considering the resources and environments. However, it is difficult to obtain the available components from these wasted display-panels. It is suggested that the difficulty in recycling the wasted display-panels derives from the fact that the liberation technology is not available.<BR>On the other hand, the electrical disintegration (ED) method using lightning discharge is introduced as a new crushing technique that can liberate materials along their boundaries.<BR>In this study, the liberation of various liquid crystal display-panels was investigated by using the electrical disintegration approach and the recovery of materials from the fragmented panel was considered. From experimental results, it was found the relationship between the display sizes and voltage, current and energy for liberation. In addition, the feasible liberation of the recycling of display-panel was achieved by the ED method. Moreover, liquid crystal and the films covered on the glass plate of the display were recovered by distillation and boiling process of fragmented display-panel.
