    Abstract: A stereoscopic image display device including a display panel including a plurality of sub-pixels arranged in a matrix defined by a horizontal direction and a vertical direction, the display panel having a changeable display direction; and a parallax unit on the display panel and including a plurality of optical elements having a tilt angle of 30° to 60° relative to the vertical direction and a pitch corresponding to a multiple of a pitch of the sub-pixels. Among the sub-pixels located to correspond to each of the optical elements, at least two sub-pixels, adjacently arranged, display the same view image.

    Abstract: Disclosed is a stereoscopic image display device which separates views from each other to reduce crosstalk and minimizes reduction in brightness due to decrease of an opening area of sub-pixels. The stereoscopic image display device includes a display panel including first and second sub-pixels arranged in parallel in the horizontal direction in each of regions formed by intersecting a plurality of gate lines and a plurality of data lines, openings for opening a part of each of the first and second sub-pixels in a light-shielding pattern configured to shield regions of the first and second sub-pixels other than the openings, and a parallax unit located on the display panel and including a plurality of lenses.

    Abstract: A liquid crystal barrier is configured to determine the viewing position of a viewer and selectively adjust based on the viewing position of the viewer. The liquid crystal barrier includes a barrier panel and a driving voltage supply unit. The barrier panel includes first electrodes, second electrodes, and liquid crystal layer. Opposite ends of the first electrodes are connected between 2n first channel lines, which form n channels, on a lower substrate. Opposite ends of the second electrodes are connected between 2n second channel lines, which form n channels, on an upper substrate. The liquid crystal layer is filled between the upper and lower substrates. The driving voltage supply unit is configured to supply at least one of a driving voltage and a common voltage to at least one of the first electrodes and the second electrodes.

    Abstract: A parallax barrier according to an example can include a first substrate and a second substrate, a liquid crystal layer between the first substrate and second substrate, at least one insulating layer on the first substrate, a first electrode on the second substrate, a second electrode and a third electrode on the insulating layer to generate electric field in order to transmit and block selectively an image, a plurality of first spacers on the first substrate, and a plurality of second spacers on the second substrate. The first spacers and the second spacers can be formed in regions corresponding to each to maintain gap between the first substrate and the second substrate. Further, the first spacers can be spaced apart from the corresponding second spacers by a predetermined distance.
