  • Patent number: 7887657
    Abstract: An apparatus for arranging a spacer includes a substrate, a roller, and an adhesion unit. The substrate includes a recessed portion. A spacer, which maintains a cell gap of a display panel and has an adhesive member formed thereon, is received in the recessed portion. The roller corresponds to the spacer. The roller makes contact with an exposed portion of the adhesive member. The adhesion unit provides for an adhesive strength between the exposed portion of the adhesive member and the roller that exceeds an adhesive strength between the received portion of the adhesive member and the recessed portion of the substrate so that the spacer may be printed on the roller. Therefore, a cell gap uniformity of a display device may be improved.
