PANEL WASHING APPARATUS AND PANEL MANUFACTURING METHOD

摘要

The present invention efficiently removes unnecessary liquid crystal and a foreign matter stuck to an outer circumferential surface or between substrates of a liquid crystal display panel comprising two substrates within a short processing time. A liquid crystal cell (a panel to be cleaned) 20a mounted on a processing stage 1 is made to be coaxially rotated in synchronization with a reference panel 5 mounted on a rotating stage 4. A cam 6 is always in contact with an end face of the reference panel 5 and, following variation of an outer circumferential surface position of the reference panel 5 in accordance with the rotation thereof, transfers in the circumference direction. Corresponding to this movement of the cam 6, a cleaning nozzle 9 arranged on the outer circumference of the liquid crystal cell 20a transfers in the circumference direction of the liquid crystal cell 20a and sprays a cleaning liquid 10 on the outer circumferential surface. Thereby the unnecessary liquid crystal and the foreign matter attached to the outer circumferential surface or between the substrates of the liquid crystal cell 20a are efficiently removed. Also in the case of changing of a size of the liquid crystal cell 20a, all that is necessary is only to change the size of the reference panel 5 into the same size as that of the liquid crystal cell 20a, and equipment down time is shortened and consequently productivity of a liquid crystal display device is improved and a manufacturing cost thereof is reduced.
