PROBLEM TO BE SOLVED: To provide a manufacturing method of a glass substrate which has an improved impact resistance upon dropping by separating a corner part of a glass substrate without giving impact to the corner part of the glass substrate, and to provide a fabrication method of an electrooptical device provided with the glass substrate. SOLUTION: The fabrication method of the electrooptical device provided with the glass substrate 1, a counter substrate opposite to the glass substrate 1 and an electrooptical material held by the glass substrate 1 and the counter substrate comprises: a process of forming a groove linearly extended in a direction intersecting two ridge lines of the glass substrate 1 extended from a corner on the vicinity of a corner part 2 including the corner of a first main surface of the glass substrate 1; a process of sticking a support to the first main surface of the glass substrate 1; and a process of etching a second main surface of the glass substrate 1 to thin the glass substrate 1 and, thereby, causing the groove to pass through the glass substrate 1 to separate the corner part 2 of the glass substrate 1 on a position where the groove is formed.
