Abstract:
1. A display device comprising: a liquid crystal panel displaying an image; a polarizer disposed on the liquid crystal panel; a liquid crystal lens disposed on the polarizer for controlling a refractive index by regions of the liquid crystal panel by use of electric field; and a polarizing member interposed between the liquid crystal lens and the liquid crystal panel, wherein an axis of light transmitted through the liquid crystal lens coincide with an optical axis of the polarizer, wherein the liquid crystal lens includes a first and a second substrates, which face each other, and a liquid crystal layer interposed between the first and the second substrates, wherein the liquid crystal lens further comprises a plurality of pixel electrodes that are separately arranged from each other on the first substrate, an insulation film disposed on the first substrate, and a plurality of common electrodes that are alternately arranged with the pixel electrodes on the insulation film, and wherein the plurality of pixel electrodes comprise a first electrode receiving a first voltage, and a second and a third electrodes which are disposed at one side of the first electrode, and respectively receive a second voltage lower than the first voltage and a third voltage lower than the second voltage.
