Patent ID: 10321121

Abstract:
The present specification provides a stereoscopic image display apparatus of which a barrier pattern arrangement can be modified according to the movement of a user. According to one example, disclosed is the stereoscopic image display apparatus comprising: an electrode on one side provided with a plurality of extended electrodes which are separated from each other; an electrode on the other side provided with a plurality of extended electrodes which are separated from each other; and a liquid crystal portion, arranged between the electrode on the one side and the electrode on the other side, for forming a barrier pattern according to an electric field or a potential difference selectively formed between the electrode on the one side and the electrode on the other side, wherein each of the extended electrodes of the electrode on the one side and each of the extended electrodes of the electrode on the other side are provided so as to overlap while in mutually corresponding positions with respect to the liquid crystal portion at the center, and wherein the barrier pattern arrangement formed on the liquid crystal portion can be modified depending on the application state of a voltage or a pulse applied to the electrode on the one side and the electrode on the other side.
