Abstract: A three-dimensional (“3D”) image display device includes a display panel, and a liquid crystal lens part disposed on the display panel and which selectively provides a two-dimensional (“2D”) image and a 3D stereoscopic image, where the liquid crystal lens part includes: a lower substrate including a plurality of linear electrodes which are disposed in different layers; an upper substrate including a plate electrode; and a lens liquid crystal layer disposed between the lower substrate and the upper substrate, where the linear electrodes in the different layers are alternately arranged in a unit zone of the liquid crystal lens part, and where two adjacent linear electrodes of the linear electrodes are spaced apart from each other when viewed from a top view.

Abstract: An image display device includes a display panel displaying an image, and a diffractive element formed to operate in a 2D mode or a 3D mode so that the image of the display panel is perceived as a 2D image or a 3D image after passing through the diffractive element. In the image display device, the diffractive element includes a first substrate and a second substrate facing each other, a first electrode layer formed on the first substrate that includes a plurality of zones, a second electrode layer formed on the second substrate, and a liquid crystal layer interposed between the first substrate and the second substrate. Further, when the diffractive element operates in the 3D mode, a common voltage is applied to the second electrode layer, and polarity of voltages applied to the first electrode layer with respect to the common voltage is inverted every zone.

Abstract: A three dimensional image display includes a display panel and a liquid crystal lens positioned on the top of the display panel. The liquid crystal lens comprises a lower substrate, an upper substrate, a lens, and an electrode voltage applying IC. The lower substrate includes a first electrode. The upper substrate includes a second electrode. The upper substrate faces the lower substrate. The lens liquid crystal layer is positioned between the lower substrate and the upper substrate. The electrode voltage applying IC is configured to form a plurality of zones on the first electrode of the lower substrate by sequentially applying first voltage and second voltage to the first electrode. The first voltage includes an overshoot voltage level. The second voltage has an inverted polarity of the first voltage.
