    Abstract: Separation lines are formed in a glass plate having first and second main surfaces by irradiating with laser light. The separation lines are configured of a product line corresponding to an outline of a glass article to be separated; and a release line. The product line includes a first in-plane void array configured of in-plane voids arranged on the first main surface; and internal void arrays for product line, each having an in-plane void. The release line includes internal void arrays for release line. A maximum length of the internal void array for product line L1max is equal to a maximum length of the internal void array for release line L2max, and a minimum length of the internal void array for product line L1min is greater than a minimum length of the internal void array for release line L2min; or the length L1max is greater than the length L2max.

    Abstract: A manufacturing method of a glass article having an organic film includes irradiating a first main surface of a glass plate having the first main surface and a second main surface, opposite each other, with a laser light of a first laser, to form an in-plane void region, in which voids are arrayed, on the first main surface, and internal void arrays, including voids arrayed from the in-plane void region to the second main surface, in the glass plate; depositing the organic film on the first main surface or the second main surface of the glass plate; and irradiating and scanning the first main surface or the second main surface, on which the organic film was deposited, with a laser light of a second laser, along the in-plane void region, to separate the glass article from the glass plate along the in-plane void region.
