Patent ID: 8284335

Claim:
An electronic display device, comprising: a display unit adapted to display an image; and a barrier unit overlapping the display unit, the barrier unit including: a liquid crystal layer between first and second substrates, the first and second substrates facing each other; a common electrode between the liquid crystal layer and the first substrate; a transparent insulation layer between the liquid crystal layer and the second substrate, the transparent insulation layer having an inner surface facing the liquid crystal layer and an outer surface facing the second substrate; a plurality of first electrodes along a first direction between the outer surface of the transparent insulation layer and the second substrate, the first electrodes being spaced apart from each other along a second direction; a plurality of second electrodes along the first direction between the inner surface of the transparent insulation layer and the first substrate; and a plurality of black layers along the first direction on lateral surfaces of the second electrodes, lateral surfaces of the second electrodes being perpendicular to a contact plane between the transparent insulation layer and the second electrodes, and the black layers overlapping portions of the first electrodes, wherein two black layers of the plurality of black layers are positioned along two respective lateral surfaces of each second electrode.
