Claims9
A device for cleaning a liquid crystal display panel including a lower substrate and an upper substrate facing each other, the lower substrate including a pad part that is free of being overlapped with the upper substrate, the device comprising:
- a brush removing foreign matters from a surface of the upper substrate,
- at least one pad part cleaning brush removing foreign matters from a pad part of the lower substrate, wherein the pad part cleaning brush is in contact with the pad part and rotates in a same direction with the brush,
- a holder holding the pad part cleaning brush;
- a driving shaft rotating the holder;
- and
- a driving motor providing a rotating force to the driving shaft,
- wherein the pad part cleaning brush has a width which is smaller than a width of the brush and is overlapped with the pad part of the lower substrate, the brush and the pad part cleaning brush can separate from the holder and are used selectively, and
- wherein a rotation axis direction of the pad part cleaning brush is same as a rotation axis direction of the brush.
A device for cleaning a liquid crystal display panel having a liquid crystal layer between upper and lower substrates, comprising:
- a first brush removing foreign matters from the upper substrate;
- a first driving shaft rotating the first brush removing foreign matters from the upper substrate;
- at least one second brush removing foreign matters from a pad part of the lower substrate, wherein the second brush is in contact with the pad part and rotates in a same direction with the first brush;
- a holder holding the at least one second brush;
- a second driving shaft rotating the holder;
- and
- a driving motor providing a rotating force to the first and second driving shafts,
- wherein the second brush has a width which is smaller than a width of the first brush and is overlapped with the pad part of the lower substrate, the first brush and the second brush can separate from the holder and are used selectively;
- and
- wherein a rotation axis direction of the second brush is same as a rotation axis direction of the first brush.
