In addition, the present invention, in the manufacturing method of the tempered glass for the touch screen panel reinforced side strength, the cutting groove for forming a cutting groove along the cut surface of the unit glass (CELL) shape on one side or both sides of the sheet glass (SHEET) Forming step (S1); And a method of manufacturing the tempered glass for side-strength reinforced touch screen panel, comprising: and a disc glass strengthening step (S2) of reinforcing the disc glass on which the cutting grooves are formed. .

On the other hand, the method of manufacturing the tempered glass for the touch screen panel reinforced side strength, the decoration and sensor forming step of forming a decoration and a sensor on the surface of the reinforced original glass (S3); And a cutting step (S4) of cutting the original glass on which the decoration and the sensor are formed in the shape of unit glass.

In addition, the disc glass strengthening step (S2), the reinforcement by forming a reinforcing layer on one side or both sides of the disc glass, it is preferable that the reinforcement layer is also formed in the cut groove of the disc glass.

Advantageous Effects of the Invention The present invention is advantageous in that durability is improved by producing a tempered glass so that the occurrence of a defective rate is less and the tempered layer is formed on the side of the unit glass to sufficiently withstand the impact from the outside.
