Claim:
A method for manufacturing a touch panel, comprising the steps of: a) selecting a glass as a substrate; an upper surface of the substrate ( 1 ) being formed with a plurality of lower electrode units ( 12 ) which are arranged in order; each lower electrode unit ( 12 ) including a transparent resistive film ( 12 A) and a bus electrode ( 12 B); a periphery of each lower electrode unit ( 12 ) being formed with a gluing frame ( 41 ), and a periphery of the substrate ( 1 ) being formed with a sealing frame ( 42 ); selecting another glass having an area corresponding to that of the substrate ( 1 ) as a panel layer; a lower surface of the panel layer ( 2 ) being formed with a plurality of upper electrode units which are arranged corresponding to those of the lower electrode units ( 12 ) of the substrate ( 1 ); each upper electrode unit ( 22 ) also including a transparent resistive film ( 22 A) and a bus electrode ( 22 B); overlaying and aligning the substrate ( 1 ) with the panel layer ( 2 ) respectively by precisely aligning method; by the gluing frames ( 41 ) and the sealing frame ( 42 ), the substrate ( 1 ) and the panel layer ( 2 ) being combined together as a combined plate; therefore, each of the upper electrode units ( 22 ) and the corresponding lower electrode unit ( 12 ) being combined together by the gluing frame ( 41 ) so as to form as an independent touch sensing unit; the lower electrode unit ( 12 ) and the upper electrode unit ( 22 ) of the touch sensing unit being arranged oppositely with a gap formed by a plurality of projected spacers ( 13 ) between the transparent resistive films ( 12 A and 22 A); by the scaling frame ( 42 ), the gap between the substrate ( 1 ) and the panel layer ( 2 ) being completely isolated from outside; etching the combined plate through a solution of hydrofluoric acid; outer surfaces of the glasses of the substrate and the panel layer being etched to be removed with a predetermined thickness; attaching at least one function film ( 6 ) to the surface of the panel layer ( 2 ) above each electrode unit so that the touch panel will have functions of polarizing and filtering; using a cutter ( 8 ) to cut the panel layer ( 2 ) and the function films ( 6 ) from an upper side thereof along a predetermined cutting line ( 25 ); a trench ( 16 ) on the substrate ( 1 ) is formed by the cutter 8 after the panel layer ( 2 ) and the function films ( 6 ) are cut through so as to divide a desired area of the touch sensing unit; and aligning a pair of a mold head ( 71 ) and a mold plate ( 72 ) to the trench ( 16 ) on the substrate ( 1 ), and a pressing force being applied through the mold head ( 71 ) from the side of the substrate ( 1 ) to brake the glass substrate through the predetermined cutting line ( 25 ) so as to separate each finished touch panel 9 .
