Abstract: A display device includes: first and second substrates; adjacent first and second color filter layers between the first and second substrates and having a first color; adjacent third and fourth color filter layers between the first and second substrates and having a second color; first and second dummy color filter layers between the first color filter layer and the second color filter layer and having the first and second colors, respectively; a first column spacer between the first dummy color filter layer and the second substrate; and a second column spacer between the second dummy color filter layer and the second substrate. The first dummy color filter has a greater height than the second dummy color filter layer. A surface of the first dummy color filter layer facing the second substrate is larger than that of the second dummy color filter layer.
