1. A three-dimensional image display apparatus comprising:
an image panel comprising pixels repeatedly arranged, each of the pixels comprising k sub-pixels in a first direction, wherein k is a natural number and Psub is an average of center distances between adjacent sub-pixels in the first direction; and a barrier panel arranged in a forward direction or a backward direction from the image panel, wherein the barrier panel comprises: a first substrate and a second substrate facing each other; a liquid crystal layer interposed between the first substrate and the second substrate; a first electrode layer between the first substrate and the liquid crystal layer, and a second electrode layer between the second substrate and the liquid crystal layer; and a plurality of walls between the first substrate and the second substrate, extending in a second direction that crosses the first direction, and arranged with an interval Pw therebetween in the first direction, wherein at least one of the first electrode layer and the second electrode layer comprises a plurality of stripe electrodes, and the barrier panel is configured to have a transmitting area and a non-transmitting area according to electric signals applied to the first and second electrode layers, and when m is a natural number that is not a multiple of k, Pw=mPsub. |
