Disclosed are a vacuum glass panel and a manufacturing method of the same. The vacuum glass panel according to the present invention includes a first glass plate, a second glass plate facing the first glass plate with a vacuum space therebetween, an edge of the second glass plate being in contact with the first glass plate, and a plurality of spacers disposed between the first glass plate and the second glass plates to separate the first glass plate and the second glass plate from each other. The plurality of spacers are formed of a glass including alumina (Al2O3) particles and silica (SiO2) particles.

1. A method of manufacturing an insulated vacuum glass panel, the method comprising: preparing a paste for a spacer, wherein the paste includes at least one of a water glass and silica sol, an alumina (Al2O3) powder, a silica (SiO2) powder, and a plasticizer, but does not include a frit;screen-print
1. A method of manufacturing an insulated vacuum glass panel, the method comprising: preparing a paste for a spacer, wherein the paste includes at least one of a water glass and silica sol, an alumina (Al2O3) powder, a silica (SiO2) powder, and a plasticizer, but does not include a frit;screen-printing the paste on one of a first glass plate and a second glass plate and drying the paste to form a plurality of spacers;laminating the first glass plate and the second glass plate with the plurality of spacers therebetween; andwelding edges of the first glass plate and the second glass plate such that the edge of first glass plate and the edge of second glass plate directly contact with each other without a frit and evacuating an internal space to form a vacuum space,wherein at least two torch parts are disposed at external sides of the edges of the first glass plate and the second glass plate due to the welding of the edges of the first glass plate and the second glass plate by melting the edges with heat from the at least two torch parts such that the at least two torch parts are disposed on opposite sides with the first glass plate and the second glass plate therebetween, and move in opposite directions,wherein the first glass plate and the second glass plate are formed of a square plate including a pair of first edges and a pair of second edges facing each other such that a first torch part and a second torch part are located at external sides of the pair of first edges, respectively,wherein the first torch part and the second torch part move in opposite directions to weld the pair of first edges, andwherein the at least two torch parts are slantly installed such that end parts toward the first glass plate and the second glass plate face upwards or downwards. 2. The method of claim 1, wherein the paste further includes a titanium dioxide (TiO2) powder, and in the paste, an amount of the alumina (Al2O3) powder is greater than an amount of the silica (SiO2) powder and the amount of the silica (SiO2) powder is greater than the amount of the titanium dioxide (TiO2) powder. 3. The method of claim 2, wherein: the paste includes at least one compound 40 wt % to 50 wt % selected from the group consisting of the water glass and the silica sol, alumina (Al2O3) powder 20 wt % to 30 wt %, silica (SiO2) powder 15 wt % to 20 wt % and plasticizer 5 wt % to 10 wt %. 4. The method of claim 1, wherein: the paste has a viscosity ranging from 2,000 cps to 20,000 cps. 5. The method of claim 1, wherein: a start position of the first torch part is an external side of one corner of the first edge, and a start position of the second torch part is an external side of the other corner of the first edge. 6. The method of claim 5, wherein: after the pair of first edges is welded, the first torch part and the second torch part move to external sides of the pair of second edges, respectively, and move in opposite directions to weld the pair of second edges. 7. The method of claim 6, wherein: a start position of the first torch part for the pair of second edges is an external side of one corner of the second edge, and a start position of the second torch part is an external side of the other corner of the second edge. 8. The method of claim 5, wherein: a third torch part and a fourth torch part are located on external sides of the pair of second edges, respectively, andthe third torch part and the fourth torch part move in opposite directions while the first torch part and the second torch part move to simultaneously weld the pair of first edges and the pair of second edges. 9. The method of claim 8, wherein: a start position of the third torch part is an external side of one corner of the second edge, and a start position of the fourth torch part is an external side of the other corner of the second edge. 10. The method of claim 8, wherein: the first torch part, the second torch part, the third torch part, and the fourth torch part simultaneously move in a clockwise direction or a counterclockwise direction. 11. The method of claim 1, wherein the water glass and silica sol have an equal property to a property of the first glass plate and the second glass plate such that the at least one of the water glass and silica sol functions as an adhesive. 12. The method of claim 1, wherein the water glass and the silica sol have an adhesive property such that the at least one of the water glass and silica sol functions as an adhesive. 13. The method of claim 1, wherein the plasticizer comprises ethylene glycol.
