Patent ID: 8823888

Claim:
A parallax barrier, comprising: a first substrate; a plurality of first electrodes disposed on the first substrate along a first direction, wherein the first electrodes are strip-shaped and electrically connected to one another; a plurality of second electrodes disposed on the first substrate along the first direction, wherein the second electrodes are strip-shaped and electrically connected to one another, and the first electrodes and the second electrodes are arranged alternately; a second substrate; a plurality of third electrodes disposed on the second substrate along a second direction and electrically connected to one another, wherein each of the third electrodes comprises at least one first portion being step-shaped; a plurality of forth electrodes disposed on the second substrate along the second direction and electrically connected to one another, wherein each of the forth electrodes comprises at least one second portion being step-shaped, and the third electrodes and the forth electrodes are arranged alternately; and a liquid crystal layer disposed between the first substrate and the second substrate.
