Description of the Invention: [Technical Field] The present invention relates to a touch panel, and more particularly to a touch panel capable of reducing a short circuit due to electrode breakage. 5 [Prior Art] Please refer to a conventional touch panel (1) shown in the first figure and the second figure, which mainly includes a first substrate (2) and a plurality of first rows disposed side by side on the first substrate (2) An ITO conductive film (3), a second substrate (4), a plurality of second conductive films (5) disposed side by side on the second substrate (4), and a plurality of first ITO conductive films disposed on the first substrate a spacer (6) between the second IT conductive films (5). When the second substrate (4) is deformed by being pressed by an external force, at least one of the first tantalum conductive films (3) in the range of the pressed portion is deformed to be in contact with the corresponding second conductive film (5). In order to produce a voltage change. However, since the first 1TO conductive film (3) is in contact with the second IT conductive film (5) as the second substrate (4) b is deformed, if the second substrate (4) is subjected to a large external force When the pressure is deformed by contact pressure for a long time, the first ΙΤ0 conductive film corresponding to the pressed portion may be broken due to stress concentration, and thus the entire first ΙΤ0 conductive film may be broken. 20 SUMMARY OF THE INVENTION The main object of the present invention is to provide a contact (four) plate which can cause short circuit or good signal due to electrode breakage. The first embodiment of the present invention provides a touch panel comprising: a plurality of first electrodes, a second substrate, a plurality of second electrodes, and a plurality of insulating layers. The first substrate has a first surface for the first electrodes to be juxtaposed; each of the first electrodes has at least one first branch; the second substrate has a second surface opposite the first surface for the first substrate The second electrodes are juxtaposed; each of the first electrodes has at least one second branch line, and the second branch line and the first branch line are parental; the insulating layer is disposed between the first electrodes and the second electrodes And having a plurality of perforations, wherein the perforations respectively correspond to the first branch line of each of the first electrodes and the second branch line of each of the second electrodes, so that the first branch line of each of the first electrodes and the second branch of each of the first electrodes The two branch lines form a touch sensing area at each of the positions of the through holes. 10 Therefore, when an external force touches any of the touch sensing regions, the first branch line corresponding to the first electrode of the touch sensing region and the second branch line of the second electrode will contact to generate a voltage change. Even if the first branch line or the second branch line is broken by an excessive external force, the main lines of the first electrodes or the second electrodes are not affected, so as to effectively avoid causing each of the first electrodes or the second portions. ^ 15 Very short circuit or poor signal. [Embodiment] In order to explain the structure, features and effects of the present invention in detail, the following preferred embodiments will be described with reference to the accompanying drawings. A touch panel (10) according to a first preferred embodiment of the present invention, the touch panel (1) includes a first substrate (20), a plurality of first electrodes (30), a second substrate (4〇), a plurality of second electrodes (5〇) and an insulating layer (60), wherein: the first substrate (20) is made of flexible poly 2010amine (p〇lyimide, ρΙ) made 201005609, which has a first surface (22). The first electrodes (30) are made of copper and each have a first main line (32), and the first main lines (32) are juxtaposed on the first substrate (20). The surface (22), and each of the first main lines (32) extends vertically from the plurality of first five branch lines (34). Referring to the fourth figure, the second substrate (4〇) is also made of flexible polyimide (PI), and has a second surface (42) opposite to the first surface (22). . The second electrode (5〇) is also made of copper, and has a second main line (52) in the shape of a long strip, and the second main lines (52) are juxtaposed on the second substrate (40). The first surface (42) is vertically interlaced with the first main lines (32), and each of the second main lines (52) extends perpendicularly from the plurality of second sub-lines (54), and each of the second sub-lines (54) Each of the first leg lines (34) is also vertically staggered. The insulating layer (60) is made of polyethylene terephthalate (PET), and is disposed between the first electrodes (3〇) and the first electrodes (50). And having a plurality of perforations (62) arranged in a matrix, as shown in FIG. 5, each of the perforations (62) corresponding to each of the first branch lines (34) and the second electrodes (50) of each of the first electrodes (10) a second branch line (54), wherein each of the first branch lines (34) of each of the first drain electrodes (30) and the second branch lines 2 (54) of each of the second electrodes (5) are formed in each of the through holes (62) The position forms a touch sensing area (4) as shown in the fourth figure. When the finger or the stylus touches any touch sensing area (64), the first branch line (34) of the first electrode (30) of the touch sensing area (64) and the second branch line of the second electrode (10) are corresponding ( 54) Will contact to produce a voltage change. If the external force received by the touch sensing area 6 201005609 (64) is too large and the first branch line (34) or the first branch line (54) corresponding to the touch sensing area (64) is broken, the first connection is broken. The first main line (32) or the second main line (52) of the branch line (34) or the second branch line (54) is still connected with other strips of the first branch line (34) or the second branch line (54), so that the proximity touch feeling 5 The area (64) can still function, so it can effectively reduce the short circuit or signal of the first main line (32) or the second main line (52) due to the break of one of the first branch line (34) or the second branch line (54). Poor transmission. The structure of the present invention can also be variously changed. For example, the touch panel (7〇) provided by the second preferred embodiment of the present invention shown in FIG. 6 has a structure different from the above-described embodiment. The first main line (82) of the electrode (80) has a plurality of trapezoidal segments (822) in a trapezoidal wave shape, and the first branch lines (84) extend from the bottom edges (824) of the trapezoidal segments (822), respectively. a second main line (92) of each of the second electrodes (9) has a plurality of tapered segments (922) and is serrated such that the first main line (82) of the first electrodes (80) When the 15th - main line (92) of the second electrode (9〇) overlaps, it will form a honeycomb-like type, as shown in the seventh figure, and the second branch lines (94) are respectively composed of the conical segments ( The tip end of 922) extends and is vertically staggered with the first branch lines (84); the perforations (1〇2) of the insulating layer (100) are also formed on the first-branch line (84) and the second electrode The second leg (94) of the electrode (90) is vertically staggered to achieve the purpose of the present invention. Although the shape of the 'first electrode and the second electrode is not limited to the above, in other words, the first electrode may be zigzag and the second electrode may be trapezoidal. The constituent elements disclosed in the foregoing embodiments are merely illustrative and are not intended to limit the scope of the present invention.
