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 θ1, 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 θ2, assuming a narrow-side angle out of intersection angles between the reference direction and an alignment axis of the second alignment film as θ3, assuming a narrow-side angle out of intersection angles between the reference direction and an absorption axis of the second polarizer as θ4, and in measuring the angles θ1, θ2, η3 and θ4 within 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 θ1, a sign of the angle θ2 and a sign of the angle θ3 are equal in one sub pixel, the angles θ1 of all sub pixels have the same sign, and the formulae (1) …
