    Abstract: A barrier panel includes a first substrate and a second substrate having block region and transmission region; a liquid crystal layer between the first and second substrates, the liquid crystal layer including a plurality of liquid crystal molecules aligned in a predetermined direction; a plurality of barrier electrodes in the block region and the transmission region of the first substrate; a common electrode on the second substrate to apply an electric field to the liquid crystal layer with the plurality of barrier electrodes; a diffraction unit in the plurality of barrier electrodes to diffract the light transmitting therethrough; and a polarization plate over the second substrate, wherein an optical axis direction of the polarization plate is parallel to the alignment direction of the liquid crystal molecule to transmit an image through an area where the electric field is not applied.

    Abstract: Disclosed herein is a holographic display which enables stereoscopic display of colors by changing a structure and mitigates a flickering effect by lowering the response speed. The holographic display may deliver an image to different positions for the left eye and right eye at the same time, thereby lowering the frequency necessary for supply of holographic image information. Thereby, the holographic display may address the issues of the afterimage effect and flickering effect in a liquid crystal panel-based spatial light modulator.

    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.
