Patent ID: 7511774

Claim:
A three-dimensional display device comprising: an image display portion adapted to display left eye images and right eye images; and a parallax barrier facing the image display portion and adapted to direct the left eye images and the right eye images displayed by the image display portion toward a left eye and a right eye of a user, respectively, wherein the parallax barrier comprises: a first substrate; a plurality of first electrodes located on the first substrate; a first connection electrode for electrically connecting the first electrodes; a first terminal electrode connected to an end of the first connection electrode; a first connection terminal connected to an end of the first terminal electrode and adapted to apply a voltage to the first electrodes and the first connection electrode; a plurality of second electrodes located between the first electrodes; a second connection electrode for electrically connecting the second electrodes; a second connection terminal connected to an end of the second connection electrode and adapted to apply a voltage to the second electrodes and the second connection electrode; a second substrate facing the first substrate; a common electrode located on the second substrate; and a liquid crystal layer located between the first and second substrates, wherein the first terminal electrode has an electric resistance lower than respective electric resistances of each of the first electrodes and the second electrodes.
