Zusammenfassung:	The present invention discloses a cutting method and a cutting stage of toughened glass with which a piece of toughened glass is divided into unit pieces of toughened glass. The cutting method cuts a piece of toughened glass which is strengthened by forming a compressive stress in the surface of a raw glass plate. The method includes the steps of reducing the central tension inside a cutting portion of the piece of toughened glass that is to be cut by concavely bending the cutting portion; and cutting the piece of toughened glass by forming a median crack in the cutting portion.
