Publication number: 20100005652Abstract: Disclosed is a method of manufacturing a wiring substrate, a tape package using the wiring substrate, and a display device using the wiring substrate. In a method of manufacturing a wiring substrate, a screen may be disposed on a base plate, the screen having openings for forming wirings. A conductive paste may be coated in the openings of the screen. A substrate may be on the screen, the conductive paste being coated in the openings of the screen. The conductive paste may be hardened to be adhered to the substrate. The base plate and the screen may be removed from the substrate to form wirings on the substrate. Because the wirings may be formed using a glass substrate having heat-resisting properties by simplified processes, thermal deflections of the substrate and dimension variations in manufacturing processes may be reduced or minimized.Type: ApplicationFiled: July 13, 2009Publication date: January 14, 2010Inventors: Dong-Han Kim, Kyoung-Sei Choi, Kyong-Soon Cho
