Abstract
An absorption axis of a polarizer on a viewer's side is set to an arbitrary direction to cope with problems attributed to polarization sunglasses or the like. Video lines extend in a reference direction as a whole while being bent locally. Assuming a narrow-side angle out of intersection angles between the reference direction and the extension direction of a portion of the video line as θ, assuming a narrow-side angle out of intersection angles between the reference direction and the extension direction of the linear portions of the first electrode as θ, assuming a narrow-side angle out of intersection angles between the reference direction and an alignment axis of the second alignment film as θ, assuming a narrow-side angle out of intersection angles between the reference direction and an absorption axis of the second polarizer as θ, and in measuring the angles θand θwithin a range from −90° to +90° from the reference direction while setting a clockwise direction as a normal direction, all of a sign of the angle θ, a sign of the angle θand a sign of the angle θare equal in one sub pixel, the angles θof all sub pixels have the same sign, and the formulae (1) 10°≦|θ1|≦|θ3| and 10°≦|θ2|≦θ3|; (2) 0°≦|θ3−θ2|≦20°; (3) 0°≦|θ1−θ2|≦2°; (4) 10°≦|θ3|≦80°; and (5) 0°≦|θ3−θ4|≦2° or 88°≦|θ3−θ4|≦92° are satisfied in all sub pixels.
