Beschreibung
Zusammenfassung:	Disclosed herein are heat treatment apparatuses and methods for liquid crystal display (LCD) cells, which are capable of rapidly transferring heat to liquid crystals injected into an LCD cell, not only to reduce the time taken for the liquid crystals to be changed into a liquid phase, but also to physically promote diffusion of the liquid crystals, thereby achieving a more uniform distribution of the liquid crystals. The apparatus includes a liquid bath, in which a liquid is contained as a medium to transfer heat to the liquid crystals in the LCD cells, a loading device to load or unload the LCD cells into/from the liquid bath, a heater installed in the liquid bath, the heater heating the liquid contained in the liquid bath and transfer heat to the liquid crystals, and a sound wave transmitter installed in the liquid bath and transmitting sound waves to the liquid crystals.
