Abstract

The scribing wheel (10) has a notch recessed portion (13) that is formed in an inclined surface (12) of a V-shaped blade from a position spaced apart at predetermined distance from a blade edge (12a). The thin and thick portions (12b,12c) are alternately formed in a front-end of the V-shaped blade. The inclined surface of the blade satisfies specific condition, when the specific angle is formed between the blade edge side portion and notch recessed portion.

Description

technical field [0001] The present invention relates to a scribing wheel, in particular to a scribing wheel which has good grip between a blade tip and a brittle substrate, and which can improve the end surface strength of the brittle substrate to be scribed. Background technique [0002] Conventionally, in the manufacturing steps of flat panel display panels such as liquid crystal display panels and organic electroluminescence (EL, electroluminescence) panels, solar cells, and the like, a step of cutting brittle material substrates such as mother glass substrates is provided. In the above cutting step, the scribing wheel is rotated on the surface of the brittle substrate to form scribed lines while applying a load in accordance with various conditions such as the material and thickness of the brittle substrate to the scribing wheel. The force cuts the brittle substrate along the scribe line, thereby manufacturing a single panel or glass substrate. [0003] As these scribin...
