Abstract
A touch device including an array substrate, at least one gate driving circuit, an opposite substrate and a shielding pattern is provided. The array substrate has a display region and a peripheral region connecting to the display region. The gate driving circuit is disposed on the array substrate and located in the peripheral region. The opposite substrate is disposed opposite to the array substrate. The shielding pattern is disposed between the array substrate and the opposite substrate. The shielding pattern projected on the array substrate is formed a first projection, the gate driving circuit projected on the array substrate is formed a second projection, the first projection at least partially overlaps with the second projection.
