PROBLEM TO BE SOLVED: To provide a display device capable of enhancing transmittance on an electrode by controlling an electric field on the electrode and using isotropic liquid crystal and a comb-tooth electrode. SOLUTION: The display device includes a pair of substrates that sandwiches a medium that is optically isotropic during no application of a voltage, but, generates optical anisotropy during the application of a voltage, where one of a pixel electrode and a common electrode is formed in a comb-tooth shape on the surface of at least one substrate, facing the other substrate. A planar electrode is formed on the counter surface of the other substrate, and a voltage having a potential equal to that of either of the pixel electrode or the common electrode is applied to the planar electrode, and a liquid crystal layer thickness d and an electrode-to-electrode distance l of the electrode formed in the comb-tooth shape establish a relation of d≥l.
