## Abstract

A touch display device includes a substrate, first light emitting units, second light emitting units, an insulation layer, and mesh units. The first and the second light emitting units are disposed on the substrate. The second light emitting units are greater than the first light emitting units in area. The insulation layer is disposed on the first and the second light emitting units. The mesh units are disposed on the insulation layer. Each of the mesh units has a mesh frame and a mesh opening. At least one of the first light emitting units and at least one of the second light emitting units are disposed in the mesh opening respectively. A gap is disposed between a first end portion of at least one of the mesh frames and a second end portion of the mesh frame, and the first end portion is electrically connected to the second end portion.
