A display panel includes: a first base substrate on which a plurality of pixel areas are defined; a color filter layer including a plurality of color filters respectively in the plurality of pixel areas of the first base substrate, where four color filters having different colors are respectively in four pixel areas adjacent to each other; a plurality of pixel electrodes on the color filter layer, respectively in the plurality of pixel areas and electrically insulated from each other; a first area including a contact point at which the four adjacent pixel areas meet; a second base substrate which is combined with the first base substrate and faces the second base substrate; and a reference electrode on one of the first and second base substrates. At least one color filter among the four adjacent color filters includes a protruding part which overlaps the first area.
