In this case, the eighth and ninth holes 241a and 241b may be formed at positions adjacent to ends of the thirteenth through twenty-fourth adhesive tape patterns 242a through 242c, 243a through 243c, 244a through 244c, and 245a through 245c, respectively. Can be. Meanwhile, in the present embodiment, two holes are formed for each adhesive tape pattern, but the holes are not limited thereto, and the holes may be two or less or more. In addition, in the present exemplary embodiment, the thirteenth through twenty-fourth adhesive tape patterns 242a to 242c, 243a to 243c, 244a to 244c, and 245a to 245c are formed on the adhesive tape sheet 210. 12 or more or less may be formed.

Although described above with reference to the drawings and embodiments, those skilled in the art can be variously modified and changed within the scope of the invention without departing from the spirit of the invention described in the claims below. I can understand.

For example, although the illustrated embodiment has been described with only a liquid crystal display as an example, the present invention is not limited thereto, and the present invention is applicable to all flat panel display devices including a panel for displaying an image and a receiving member that protects the panel and has an opening. Can be.

As described above, according to the present invention, since the adhesive tape patterns attached to the liquid crystal display panel and the upper housing member are separately manufactured, a larger number of adhesive tape patterns can be manufactured from the adhesive tape sheet having the same shape than in the related art, thereby reducing the cost. .

In addition, by forming a hole in the release paper of the area spaced apart from the adhesive tape pattern by a certain distance, the adhesive tape automatic attachment device can recognize the position of the adhesive sheet.
