Abstract
A pair of supporting arms are rotatably attached to both ends of a fixed shaft. A supporting shaft extends across forward ends of the supporting arms and in parallel to the fixed shaft. A grinding roller on which an abrasive tape is arranged, and guide rollers sandwiching it are attached to this shaft. Axial centers of the grinding roller and the guide rollers are in an eccentric state. Thus when the guide rollers contact a color filter, a gap is given between the grinding roller and the color filter, and projections can be ground corresponding to the gap.
