Abstract
A rubbing direction (X) for each upper substrate of a tile panel constituting a liquid crystal panel unit is set along a horizontal direction (H) of the liquid crystal panel unit, a rubbing direction (Y) for each lower substrate of the tile panel is set along a vertical direction (V) thereof, and absorption axes (S) of polarizing plates and are allowed to coincide with the horizontal direction (H) of the liquid crystal panel unit. Moreover, in a set of four tile panels, the rubbing directions (X) and (Y) are made to differ from one another, thus viewing directions (Z) of high contrast are distributed into four directions, and turning directions (reference codes (R) and (L)) of liquid crystal molecules in the respective tile panels are arranged alternately in the horizontal direction (H) of the liquid crystal panel unit.
