Abstract:
A liquid crystal parallax barrier panel has the structure formed by stacking an electrode substrate, a liquid crystal layer and a sealing substrate in order. The electrode substrate includes a glass substrate, a first electrode which is branched in plural stages, a second electrode which is arranged on the same layer as the first electrode and is branched in plural stages, and an alignment film. Out of the first electrode and the second electrode, twig portions which include distal ends of branched portions of one electrode and twig portions which include distal ends of branched portions of another electrode are alternately arranged such that the twig portion which includes the distal end of the branched portion of one electrode enters between two twig portions which include the distal ends of branched portions of another electrode. In a state where slits are not formed in a parallax barrier, the first electrode and the second electrode have the same voltage, while the slits are formed in the parallax barrier when a predetermined voltage is applied to the first electrode.
