A touch display device is provided in some embodiments of the present disclosure, including a transparent cover, a patterned touch sensing film layer, a light-shielding layer, and a UV-blocking layer. The patterned touch sensing film layer covers a first surface of the transparent cover. The light-shielding layer is located between the transparent cover and the patterned touch sensing film layer. The UV-blocking layer prevents UV from irradiating the light-shielding layer. The UV-blocking layer is located between the light-shielding layer and the patterned touch sensing film layer and covers the light-shielding layer. A method of forming a touch display device is also provided. The touch display device and formation method thereof provided in some embodiments avoid the injury of the light-shielding layer caused by the laser by disposing of the UV-blocking layer in the single-side electrode structure, which replaces the wet etching steps and decreases the cost of the etching steps.

Touch display device and formation method thereof

A touch panel includes a thin-film substrate, a first conductive layer, and a second conductive layer. The thin-film substrate has a display region and a peripheral region defined thereon, has a first surface and a second surface opposite to each other, and has a thickness. The first conductive layer is disposed on the first surface and includes a plurality of first traces disposed in the peripheral region. The second conductive layer is disposed on the second surface and includes a plurality of second traces disposed in the peripheral region. The thin-film substrate has at least one groove at an interlaced region between one of the first traces and one of the second traces. The groove is in one of the first surface or the second surface and has a depth. The depth is between about 2.5 &#x3bc;m and about one-half of the thickness.
