A display device includes a first base substrate, a second base substrate, a liquid crystal layer, a conductive protrusion structure and an electrode structure. The second base substrate is disposed opposite to the first base substrate. The liquid crystal layer is disposed between the first and second base substrates. The conductive protrusion structure is disposed on one of the first and second base substrates. The electrode structure is at least disposed on the first or second base substrate having the conductive protrusion structure.
