In the embodiment, the plurality of hole structures 217 are penetrated through the insulating layer 213. . Referring to FIG. 10, a second insulating layer 213b is formed in the plurality of hole structures 217. The material of the first insulating layer 213b is different from the material of the insulating layer 213, and the thickness of the second insulating layer 213b is smaller than the depth of the hole structure 217. .

Since the thickness of the first insulating layer 213b is smaller than the depth of the hole structure 217, the portion of the at least partial second electrode line 216 located in the hole structure 217 is recessed in the hole structure 217. Further, it is well known to those skilled in the art that a semiconductor layer (not shown) is formed on the insulating layer 213 as a channel layer of the plurality of thin film transistors 212 before the second electrode line 216 is formed. Thereafter, the second insulating layer 213b is selectively etched by a wet etching process to expose the first electrode lines 214, and the insulating layer 213 is not etched, thereby causing the at least a portion of the second electrode lines 216 and the first electrode. The overlapping positions 215 of the lines 214 respectively form a hollow structure 2151 (shown in FIG. 4), and a touch type electronic paper display device 2 can be manufactured. It is claimed that the second insulating layer 2i3b may be partially or partially etched away after 201023020, as long as the first electrode lines 214 are exposed. In summary, the embodiment of the present invention forms a hollow structure 2(5)' by respectively forming the structure "λ» of the thin film transistor substrate 21 at an overlapping position 215 of at least a portion of the first electrode line 216 and the first electrode line 215. When an external force is applied to the second electrode line 216, the second electrode line 216 can be bent downward to be in contact with the first electrode line, so that the first electrode line 214 and the second electrode line 216 can respectively serve as mutual display functions. In addition to the scanning line and the data line, the first side line and the second side line which are mutually intersected by the hard-working panel Wei Wei; respectively, in other words, the first-electrode line 214 is switchable. As the sweeping cat line and the first detecting line, the second electrode line 216 is switchable as the data line and the second line. The touch-type electronic paper device 21 of the touch-type electronic paper device 2G can be manufactured by using a well-established semiconductor process. Therefore, the touch-type electronic paper device 2 and the manufacturing method thereof can be relatively low. Manufacturing costs. In addition, the structure of the first electrode line 214 and/or the second electrode line 216 of the aforementioned implementation is appropriately changed as shown in FIG. 12, and the 电极 may be located in the hole structure of the first electrode line 214. Portions of 217 (i.e., portions corresponding to overlapping locations 215) are formed with upwardly extending bumps 2142. Further, when the bump 2142 is sufficiently high, as shown in FIG. 13, the portion of the second electrode line 216 located in the hole structure 217 may not need to be recessed in the hole structure 217, that is, the second electrode line 216 is located in the hole structure. The portion of the portion 217 is straight (ie, flat). The lower surface 2162 is coplanar with the upper surface 2132 of the insulating layer 213; correspondingly, during the manufacturing process of the touch-sensitive electronic paper display device 2 The thickness of the second insulating layer 213b (see FIGS. 10 and u) is set to be equal to the depth of the hole structure 217 instead of being less than the depth of the hole structure 217 as described above. Of course, 9 201023020; for example, the bumps 2142 shown in Figures 2 and 51 13 can be located according to actual needs: ? 丨 ~ surname 14 and Figure 15, when the second electrode line 216 When the portion of the structure 217 is flat or convex, it can also be turned down/, and the electrode line 214 is in contact with the conduction, and the bump 2142 can be omitted. The present invention has been disclosed in the preferred embodiments as described above. However, it is not intended to be limiting, and X is a person skilled in the art, and applies for modification and retouching without departing from the spirit of the present invention. The protection axis of the invention is subject to the definition of the range of the stomach after the sight.
