The present invention relates to an attaching roller device for attaching a film, such as a polarizing plate, onto a display panel with high accuracy and, more specifically, to an attaching roller device for attaching a film onto one surface of a display panel. The attaching roller device is made up of a pair of rollers into which a display panel and a film are inserted. A first roller which is in contact with the display panel, among the pair of the rollers, is a heating pressure roller for generating a certain amount of heat, and the second roller is a pressure roller. According to the attaching roller device suggested in the present invention, as a certain amount of heat is generated on the roller which is in contact with the display panel, among the pair of the rollers for attaching the film such as a polarizing plate onto the display panel, while the pressurization force of the roller is reduced, the heat is transferred to the polarizing plate and facilitates attachment so that previous problems due to excessive pressurization force can be resolved and the film such as the polarizing plate can be attached onto the display panel with high accuracy. Also, as heat generated by a heating member which is a heating element is transferred through heating medium oil, the heat is uniformly transferred to the entire outer surface of the roller and thus the heat is uniformly applied when the display panel and the film are attached so that the film can be attached onto the display panel with high accuracy.
