       7 . The boss assembly as claimed in  claim 6 , wherein the shank spinning portion extends from the shank support portion within the cylindrical cavity and extends beyond the reinforcing collar spinning portion.  
   
   
       8 . The boss assembly as claimed in  claim 6 , wherein the reinforcing collar support portion includes an inner member that defines an end wall of the cylindrical cavity, 
 the inner member has a hole defined therein, an inner diameter of the hole being less than an inner diameter of the cylindrical cavity,    the shank extends through the hole, and    the shank support portion is disposed against the inner member.    
   
   
       9 . The boss assembly as claimed in  claim 1 , wherein the shank includes a shank spinning portion and a shank support portion disposed adjacent to the shank spinning portion, the shank support portion having a larger diameter than the shank spinning portion, 
 the reinforcing collar includes a reinforcing collar spinning portion and a reinforcing collar support portion disposed adjacent to the reinforcing collar spinning portion, the reinforcing collar support portion having a larger diameter than the reinforcing collar spinning portion, the reinforcing collar spinning portion being tubular and defining a cylindrical cavity, and    the cylindrical cavity is filled by the shank spinning portion, the shank spinning portion having an outer diameter that is substantially equal to an inner diameter of the cylindrical cavity.    
   
   
       10 . The boss assembly as claimed in  claim 9 , wherein the reinforcing collar support portion and the shank support portion are configured to extend parallel to the front side of the bracket, and 
 the reinforcing collar support portion is configured to be disposed between the front side of the bracket and the shank support portion.    
   
   
       11 . A display device, comprising: 
 a main body having a bracket mounted thereto; and    a boss assembly having multiple spun parts fixed through a through-hole in the bracket, the boss assembly including: 
 a shank; and  
 at least one reinforcing collar disposed on the shank,  
   wherein the shank and the reinforcing collar pass through the through-hole, such that the shank and the reinforcing collar protrude beyond the bracket, and    the shank and the reinforcing collar are spun by a spinning process so as to fix the boss assembly to the bracket.    
   
   
       12 . The display device as claimed in  claim 11 , wherein the display device is a plasma display device.  
   
   
       13 . A method of mounting a boss assembly having multiple spinning parts to a bracket, the method comprising: 
 providing a bracket having a through-hole therein;    providing the boss assembly, the boss assembly including a shank having a reinforcing collar disposed thereon;    inserting the reinforcing collar and the shank through the through-hole of the bracket from a front side of the bracket; and    performing a spinning process on a spinning portion of the reinforcing collar and a spinning portion of the shank that protrude through the bracket, so as to fix the reinforcing collar and the shank to the bracket.    
   
   
       14 . The method as claimed in  claim 13 , wherein the spinning process comprises: 
 a first fixing operation to fix the shank to the reinforcing collar; and    a second fixing operation to fix the reinforcing collar and the shank to the bracket.    
   
   
       15 . The method as claimed in  claim 14 , wherein the first and second fixing operations are performed through a single spinning process.  
   
   
       16 . The method as claimed in  claim 14 , wherein the reinforcing collar spinning portion defines a cylindrical cavity, 
 the shank spinning portion is disposed within the cylindrical cavity and extends beyond an end of the cylindrical cavity,    the shank spinning portion has an outer diameter that is smaller than an inner diameter of the cavity, so as to define a cylindrical space between the outer diameter of the shank spinning portion and the inner diameter of the cavity, and    the first fixing operation spins the shank spinning portion to form a first shank spun portion, wherein the first shank spun portion fills the cylindrical space.    
   
   
       17 . The method as claimed in  claim 16 , wherein the first shank spun portion does not extend beyond the end of the cylindrical cavity.  
   
   
       18 . The method as claimed in  claim 14 , wherein the reinforcing collar spinning portion defines a cylindrical cavity, 
 the shank spinning portion is disposed within the cylindrical cavity and extends beyond an end of the cylindrical cavity,    the shank spinning portion has an outer diameter that is substantially equal to an inner diameter of the cavity, so as to fill the cavity, and    the first fixing operation spins the shank spinning portion to form an first shank spun portion, wherein the first shank spun portion is disposed beyond an end of the reinforcing collar spinning portion.    
   
   
       19 . The method as claimed in  claim 13 , wherein a support portion of the reinforcing collar is disposed against the front side of the bracket.  
   
   
       20 . The method as claimed in  claim 19 , wherein a support portion of the shank is disposed against a front side of the reinforcing collar support portion, such that the reinforcing collar support portion is disposed between the front side of the bracket and the shank support portion.
