PURPOSE:To perform boring work with an excellent processing shape without damaging a bonding agent layer. CONSTITUTION:A mask plate frame body 30 is configured by forming a red reflection stripe filter 17 and a blue reflection stripe filter 18 on one surface of a transparent glass substrate 16 and bonding a transparent glass substrate 29 using a bonding agent layer 19 so as to interpose both filters 17 and 18 therebetween. A hole 31 is bored up to almost the half of the thickness of both substrates 16 and 29 from the transparent glass substrate 16 to the transparent glass substrate 29 and a glass rod 32 is inserted and fixed. Then the top 32a of the glass rod 32 is broken away. Besides, the transparent glass substrate 29 is ground. Subsequently, after the said grinding is completed, a thru hole 34 is formed and a desired faceplate frame body 21 is obtained by removing the glass rod 32 with the use of a narrow wire or the like while keeping the whole mask plate frame body 30 at 100-120 deg.C again. |
