圖5的觸控顯示裝置10C的構件大致相似於圖2的觸控顯示裝置10A，兩者的差異主要在於：本實施例將觸控層200與網狀電極層300製作於彩色濾光基板120的外表面上，此為顯示面板上(on cell)架構。詳細地說，在本實施例中，觸控顯示裝置10C包括顯示層100、觸控層200、網狀電極層300、主動陣列基板110以及彩色濾光基板120。觸控層200與網狀電極層300配置於彩色濾光基板120的外表面120a上，且網狀電極層300配置於觸控層200與彩色濾光基板120之間。顯示層100配置於彩色濾光基板120的內表面120b上，且顯示層100配置於主動陣列基板110與彩色濾光基板120之間。在本實施例中，觸控層200的下方配置有作為屏蔽結構的網狀電極層300，因此網狀電極層300可以隔絕諸如來自顯示層100的雜訊影響觸控層200，以提升訊號雜訊比，使得觸控顯示裝置10C具有良好的觸控品質。 The components of the touch display device 10C of FIG. 5 are substantially similar to those of the touch display device 10A of FIG. 2 . The difference between the two is mainly that the touch layer 200 and the mesh electrode layer 300 are formed on the color filter substrate 120 .

M2 is, for example, located on the inner surface 500b of the substrate 500. In detail, the first conductive layer M1 includes a first sensing pattern 212 and a first bridge line 214. In this embodiment, The first conductive line 230 is also disposed on the substrate 500, for example, and is electrically connected to the first sensing series 210. The second conductive layer M2 includes a plurality of second conductive patterns 221b, a plurality of shield patterns 226, and a plurality of second bridge lines 224. The second conductive line 240 is also disposed on the second substrate 510 , for example, and is electrically connected to the second sensing series 220 .

基板500作為絕緣層配置於第一感測圖案212與屏蔽圖案226之間。也就是說，第一感測圖案212的下方配置有屏蔽圖案226，且第一感測圖案212與屏蔽圖案226之間例如是更配置有基板500，因此屏蔽圖案226可以隔絕諸如來自顯示層100的雜訊影響第一感測圖案212，以提升訊號雜訊比，使得觸控顯示裝置20B具有良好的觸控品質。再者，由於屏蔽圖案226與第二感測圖案222在同一道製程中完成，因此實質上不會增加現有製程的光罩數目。因此，屏蔽圖案226的製作可以輕易地與現有觸控層的製程結合且不會大幅增加觸控顯示裝置的製作成本。綜上所述，本發明的觸控顯示裝置包括顯示層、觸控層以及配置於顯示層與觸控層之間的網狀電極層或屏蔽圖案。作為屏蔽結構的網狀電極層或屏蔽圖案能隔絕雜訊，以提升訊號雜訊比，使得觸控顯示裝置具有良好的觸控品質。在上述的一實施例中，是藉由製作傳導線路或橋接線等金屬導線製程同時製作網狀電極層，也就是說，網狀電極層是利用現有的觸控層製程中的金屬導線製程完成。在另一實施例中，利用感測圖案的製程同時製作屏蔽圖案，以屏蔽另一膜層的感測圖案受到雜訊干擾。因此，網狀電極層或屏蔽圖案的製作實質上不會增加現有製程的光罩數目。 The substrate 500 is disposed as an insulating layer between the first sensing pattern 212 and the shield pattern 226. That is, the shielding pattern 226 is disposed under the first sensing pattern 212, and the substrate 500 is disposed between the first sensing pattern 212 and the shielding pattern 226, for example, so that the shielding pattern 226 can be isolated, such as from the display layer 100. The noise affects the first sensing pattern 212 to enhance the signal noise ratio, so that the touch display device 20B has good touch quality. Moreover, since the shielding pattern 226 and the second sensing pattern 222 are completed in the same process, the number of masks of the existing process is not substantially increased. Therefore, the fabrication of the shield pattern 226 can be easily combined with the process of the existing touch layer without significantly increasing the manufacturing cost of the touch display device. In summary, the touch display device of the present invention includes a display layer, a touch layer, and a mesh electrode layer or a shielding pattern disposed between the display layer and the touch layer. The mesh electrode layer or the shielding pattern as the shielding structure can isolate the noise to improve the signal noise ratio, so that the touch display device has good touch quality. In an embodiment described above, the mesh electrode layer is simultaneously fabricated by fabricating a metal wire process such as a conductive line or a bridge wire. That is, the mesh electrode layer is completed by using a metal wire process in the existing touch layer process. . In another embodiment, the mask pattern is simultaneously fabricated using the process of sensing the pattern to shield the sensing pattern of the other layer from noise interference. Therefore, the fabrication of the mesh electrode layer or the shield pattern does not substantially increase the number of masks of the existing process.

因此，網狀電極層或屏蔽圖案的製作可以輕易地與現有觸控層的製程結合且不會大幅增加觸控顯示裝置的製作成本。如此一來，網狀電極層或屏蔽圖案的配置可以達到隔絕雜訊的目的，且不會大幅增加觸控顯示裝置的製作成本。因此，觸控顯示裝置具有良好的觸控品質。再者，網狀電極層或屏蔽圖案的設置亦能進一步避免觸控層影響共用電極的靜電放電防護能力，使得觸控顯示裝置亦具有良好的顯示品質。 Therefore, the fabrication of the mesh electrode layer or the shielding pattern can be easily combined with the process of the existing touch layer without significantly increasing the manufacturing cost of the touch display device. In this way, the configuration of the mesh electrode layer or the shielding pattern can achieve the purpose of isolating the noise, and does not greatly increase the manufacturing cost of the touch display device. Therefore, the touch display device has good touch quality. Furthermore, the arrangement of the mesh electrode layer or the shielding pattern can further prevent the touch layer from affecting the electrostatic discharge protection capability of the common electrode, so that the touch display device also has good display quality.
