DISPLAY AND FILED-OF-VIEW ANGLE CONTROL DEVICE USED IN THE SAME

摘要

A display includes a field-of-view angle control liquid crystal panel (2) arranged at least one of the rear surface and the front surface of a display device so that the display can be applied to various use environments by switching the display state between a wide filed-of-view angle and a narrow field-of-view angle. The field-of-view angle control liquid crystal panel (2) includes: a liquid crystal cell (21) which hybrid-orientates a liquid crystal between orientation films (212a, 212b) arranged on a pair of light transmitting substrates, respectively; and a drive circuit for applying voltage to the liquid crystal layer of the liquid crystal cell (21). The liquid crystal cell (21) is arranged between two polarizing plates (13, 22) arranged so that the polarized transmission axes (X<SUB>13</SUB>, X<SUB>22</SUB>) intersect substantially orthogonally. The drive circuit switches the display state between the wide field-of-view angle and the narrow field-of-view angle by changing the orientation state of liquid crystal molecules (213p) of the liquid crystal layer of the field-of-view angle control liquid crystal panel (2).
