DISPLAY AND FIELD-OF-VIEW ANGLE CONTROL DEVICE USED FOR THE SAME

摘要

A display can be applied to various use environments and applications by switching the display state between a wide field-of-view and a narrow field-of-view. The display includes a field-of-view angle control liquid crystal panel (2) on a rear surface or a front surface of the display device. The field-of-view angle control liquid crystal panel (2) includes: a liquid crystal cell (21) having liquid crystal molecules (21c) homogeneously oriented between a pair of light transmitting substrates (21a, 21b); and a drive circuit for applying voltage to a 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 polarization transmission axes (X<SUB>13</SUB>, X<SUB>22</SUB>) substantially orthogonally intersect each other. 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 the liquid crystal molecules (21c) of the liquid crystal layer of the field-of-view angle control liquid crystal panel (2).
