CONSTITUTION: A reamer bolt coupling structure comprises a reamer bolt(56) which is coupled prior to a coupling bolt(60); a coupling hole(54a) formed at a first member(50) where the reamer bolt penetrates and mounted; a mounting groove(52) formed at a second member(54) in such a manner that the reamer bolt is coupled, passing through the coupling hole; and an insertion member(58) interposed between a head portion(56a) of the reamer bolt and the top surface of the coupling hole, such that the reamer bolt is coupled prior to the coupling bolt. The reamer bolt includes the head portion which gets caught at the top surface of the coupling hole; a body portion(56b) contacting the inner wall of the coupling hole; and a coupling portion(56c) coupled to the first member.

Abstract: PURPOSE: A rubbing device for an LCD and a method for rubbing an orientation film are provided to reduce the disclination and the light leakage caused by the bad rubbing by rubbing the entire surface of an orientation film with two rubbing rollers which rotate oppositely. CONSTITUTION: A rubbing device for an LCD includes a moving table(10) to secure a substrate(20), and first and second rubbing rollers(31,32) rotating oppositely and rubbing the substrate in contact with the surface of the substrate, wherein the first and second rubbing rollers are positioned in parallel with a predetermined distance and wound with rubbing sheet(33,34) for contacting an orientation film for forming pretilt angle on the surface of the orientation film.
