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.
