PROBLEM TO BE SOLVED: To provide a manufacturing method of a display panel which makes a joining force, which is applied along peripheral parts of a sealing lid and a glass substrate, constant with simple work.SOLUTION: In a manufacturing method of a display panel 1 according to this invention, a recessed groove 17 is formed at a peripheral part 41 of a glass substrate 3, and a glass welding rod 7, which is formed into a long shape having a circular cross section, has a melting point lower than a sealing lid 5 and the glass substrate 3, and may be melted by radiation of a laser beam 45, is placed along the recessed groove 17. The laser beam 45 is radiated to the glass welding rod 7 to melt the glass welding bar 7. The melted glass welding bar 7 is housed in the recessed groove 17 and is solidified. A peripheral part of the sealing lid 5 is joined to a peripheral part 41 of the glass substrate 3 while closely contacting therewith through the above-described processes. |
