Abstract
Example embodiments relate to a multi-dimensional image selectable display device having an image panel adapted to output an image, and a barrier panel at an upper-side portion of the display device so as to display the image as a two dimensional image or a three dimensional image. The barrier panel may include a first substrate having a first electrode and a second electrode arranged so as to apply a horizontal between the first and second electrodes, a second substrate, and a liquid crystal layer between the first and second substrates. A phase delay value Δn*d may range from approximately 700 to 800 nm, wherein the phase delay value Δn*d may be a product of a double refraction value Δn of a liquid crystal constituting the liquid crystal layer, and a cell gap d between the first and second substrates.
