Claim:
1. A touch display device, comprising: a display module; a polarizer; a first patterned electrode layer disposed between the polarizer and the display module and including a patterned portion and a non-patterned portion; and a first transparent adhesive layer disposed on the first patterned electrode layer, wherein the refractive index of the first transparent adhesive layer is greater than or equal to 1.65 and less than or equal to 1.72; wherein the first transparent adhesive layer is disposed between the polarizer and the first patterned electrode layer, wherein the first transparent adhesive layer has a first surface and a second surface which are disposed oppositely, the first surface faces the polarizer and the second surface faces the first patterned electrode layer, the refractive index of the second surface is greater than that of the first surface, and the stickiness of the first surface is greater than that of the second surface; wherein reflectivity of the patterned portion is substantially the same as reflectivity of the non-patterned portion.
