  • Patent number: 9229258
    Abstract: A to-be-cut liquid crystal mother panel includes a TFT mother substrate forming at least one voltage-applying area onto which an external voltage is applied, a CF mother substrate arranged corresponding to the TFT mother substrate, and a pressure-reduction member located between the CF mother substrate and the TFT mother substrate; the pressure-reduction member corresponds to the voltage-applying area for reducing an adsorptive force between the voltage-applying area and an end portion of the CF mother substrate corresponding to the voltage-applying area. The pressure-reduction member increases the surface roughness of the end portion, avoids a vacuum state formed between the end portion and the voltage-applying area, reduces the adsorptive force between the end portion and the voltage-applying area, and allows the splitting device to separate the end portion from the TFT mother substrate easily after the liquid crystal mother panel is cut.
