Patent ID: 7986283

Claim:
A multi-dimensional image selectable display device, comprising: an image panel adapted to output an image; and a barrier panel at an upper-side portion of the display device adapted to display the image as a two dimensional image or a three dimensional image, the barrier panel includes: a first substrate having a first electrode and a second electrode adapted to generate a horizontal electric field between the first and second electrodes; a second substrate having a transparent electrode adapted to generate a vertical electric field between the first and second substrates; and a liquid crystal layer between the first and second substrates, wherein: the barrier panel has at least three modes, a three dimensional image mode, a two dimensional image of a wide viewing angle mode, and a two dimensional image of a narrow viewing angle mode; and the barrier panel is adapted to have the two dimensional image of the narrow viewing angle mode when the vertical electric field is generated between the first and second substrates to distort liquid crystals of the liquid crystal layer at a predetermined angle such that a phase delay value Δn*d ranges from approximately 700 to 800 nm, the phase delay value Δn*d being 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.
