A display device comprises a first substrate, a second substrate, a touch sensing layer, a first polarization layer and a second polarization layer. The second substrate is disposed opposite the first substrate. The touch sensing layer is disposed on the first substrate. The first polarization layer is directly connected to the touch sensing layer through a first adhesive element. The second polarization layer is connected to the side of the second substrate away from the first substrate through a second adhesive element. The thickness of the first polarization layer or second polarization layer is between 5 μm and 50 μm.
