ABSTRACT:
A method of injecting liquid crystal for producing a liquid crystal display panel, in which the liquid crystal is injected into a cell of an LCD panel after the liquid crystal is purified by adding ionic material captures for capturing ionic material which increases the contamination degree of the liquid crystal, into the liquid crystal contained in a liquid crystal tray having a contact coil formed at the upper part thereof. According to the method of the present invention, the specific resistivity of the liquid crystal is prevented being lowered down and the number of times of injecting the liquid crystal into a cell of an LCD panel is decreased because the contamination of the liquid crystal contained in the liquid crystal tray by ionic material in producing the LCD panel is restrained.
