고콘트라스트의 플랫 패널 디스플레이의 유리 기판으로서, 투광성을 갖지 않고, 긴 변 길이가 50㎛를 초과하고, 짧은 변 길이가 5㎛ 미만인 내부 결함과, 상기 내부 결함의 위치에 대응하는 상기 유리 기판의 주 표면 상의 위치에, 상기 주 표면으로부터의 높이가 0.15㎛ 미만인 볼록부를 갖는 유리 기판을 사용한다. As a flat panel display glass substrate having a high contrast, the present invention uses a glass substrate that has: an internal defect, which does not have translucency, and which has a long-side length longer than 50 μm, and a short-side length shorter than 5 μm; and a protruding section, which is at a position on a main surface of the glass substrate, said position corresponding to the position of the internal defect, and which has a height shorter than 0.15 μm from the main surface.
