Field of the Invention The present invention relates to a touch panel having a larger area than a lower conductive layer of a conductive layer and a substrate. [Previous technology] Generally, the touch panel includes an upper conductive layer and a lower control panel, and the process yield is good or bad, and the transparent transparent soil that has been touched by electricity is related to whether or not the coating is coated. · Furthermore, after the coating of the upper conductive material is completed, the conductive forming of the upper and lower layers of the transparent conductive layer of the transparent layer of the electrical layer requires the printing of the wires and the sizing action, and finally The second flexible circuit board is pressed between the upper and lower conductive layers - between the sides. However, the soft circuit (4) has a thickness, which will change the thickness of the transparent conductive material coated by the touch precision, especially pushing the lightning-based transparent conductive material upward, resulting in the influence of the conductive layer on the overall flatness. Forming a conductive layer-side ridge, and ο to solve the above disadvantages, the upper conductive layer can be further disposed - the protective layer is attached to the upper conductive film by an adhesive layer, and the adhesive The layer corresponds to the position of the flexible circuit board - a gap in the adhesive to accommodate the upper portion of the film that is pushed up by the flexible circuit board. Electricity is actually applied to the general consumption of a single overall planar effect. It is the range of the visible area and the active area that the smuggling layer of the smuggling layer is beyond the reach of the squatting surface, but by (4) the touch layer of the protective layer The adjacent regions outside the structure, the isoelectric layer and the surface of the protective layer on the side 2 of the touch structure in the same plane 'will be likely to cause creases at the edges, affecting the appearance of the overall plane 4 200947278. SUMMARY OF THE INVENTION In view of the above, the main object of the present invention is to provide a touch panel having a conductive layer having a larger area than a lower conductive layer and a substrate disposed on the lower layer, and reducing the surface of the protective layer on the touch structure. The main technical means used for the purpose of the crease of the crease is that the touch surface φ plate comprises: a lower conductive layer; a spacer layer is disposed on the lower conductive layer and the side thereof is formed with a defect An upper conductive film is disposed on the spacer layer, the upper conductive film has a larger area than the spacer layer and the lower conductive layer and partially extends from a side of the spacer layer; and a flexible circuit board has a connection end, The connection end is sandwiched between the lower conductive layer and the upper conductive film corresponding to the gap. The upper conductive layer may be a conductive glass substrate or a substrate and an upper conductive film disposed on the substrate. The present invention may further comprise a protective layer having an area shape corresponding to the upper conductive film, the protective layer being attached to the upper conductive film by an adhesive layer, and the adhesive knee layer corresponding to the position of the flexible circuit board Glue σ to accommodate the portion of the upper conductive film that is pushed up by the flexible circuit board. Furthermore, in order to attach the protective layer to the upper conductive film, the air in the rubber port can be smoothly discharged. The present invention further forms an opening in the upper conductive film corresponding to the position of the rubber mouth to help the inside of the rubber mouth. The air displaced by the protective layer is discharged through the opening. When a large area of the upper conductive film is disposed on the lower conductive layer and the upper layer of the lower layer, when the protective layer is attached to the upper conductive film, the surface of the protective layer is less likely to be spaced along the lower surface due to the extension of the area of the upper conductive film. The side edges of the lower layer stack structure such as the lower conductive layer form a significant crease.

The rubber port (6 1) and the upper conductive layer are formed as described above. The opening (3 1 ) of the film (3 〇) is connected, and when the protective layer (5 ◦) is attached to the upper conductive film (30), the glue port (6 1) is squeezed at the adhesive layer (60). The air can be discharged through the opening (3 1 ) so that the rubber (6 1 ) does not cause the protective layer (50) to bulge at this position due to the inability to discharge the air. 7 200947278 In summary, the upper surface of the present invention is electrically conductive. The film system is designed to have a large area. When a protective layer is disposed on the surface of an adhesive layer, the surface of the protective layer is extended, so that the surface of the protective layer is not easily along the lower layer of the lower spacer layer and the lower conductive layer. The side of the stacked structure forms a clear crease; further, the adhesive layer is formed with a glue opening corresponding to the position of the flexible circuit board to accommodate the raised portion of the conductive film pushed by the flexible circuit board, and The upper conductive film forms an opening for connecting the adhesive opening, so that when the protective layer is applied on the adhesive layer, the flatness of the upper conductive film is not affected by the bulging of the upper conductive film and the air in the rubber mouth, thereby achieving the entire touch panel Full plane.
