An exemplary display device includes a substrate, a plurality of first and second pixel units, a first display layer, a second display layer, a spacer and a first color filter. The substrate has a first and a second display region. The first and second pixel units are disposed in the first and second display regions, respectively. The first display layer and the second display layer are disposed on the first and second pixel units, respectively. The first display region is surrounded by the spacer therefore the first display layer is separated from the second display layer. The first color filter is disposed on the first display layer. The first display layer and the second display layer are based on different displaying mechanisms. Therefore, the display device has the advantages of both the first display layer and the second display layer.
