Abstract
A viewing angle control panel (2) that includes two substrates (4 and 6) facing each other and liquid crystal layer (5) provided between the substrates and that is usable in combination with a display panel (10) so as to allow a liquid crystal display device (1) to switch a viewing angle characteristic, wherein: one of the substrates (6) includes a counter electrode pattern (62) in which a counter electrode is provided over the one of the two substrates; and the other one of the substrates (4) includes a transparent electrode pattern (49) in which transparent electrodes (49a through 49d) are provided in a striped manner and first and second wire electrodes (e.g., wire electrodes 48a and 48b) that are provided for each space (e.g., a space 51x) between the transparent electrodes in the transparent electrode pattern (49) in such a manner that the first the second wire electrodes, positioned in parallel with the transparent electrodes, respectively, overlap the space 51x. In the arrangement, electric potential settings of wiring electrodes (48a through 48f) are changed. This makes it possible to switch a visibility limitation direction.
