Claim Text:
1. A liquid crystal display apparatus comprising: a first substrate; a second substrate; a liquid crystal layer put between the first substrate and the second substrate; an array of sub-pixels arrayed in a first direction and a second direction, the first direction and second direction being perpendicular to each other, each of the sub-pixels including an opening section or opening sections whose total length taken along the first direction at each of positions ranging in the second direction is almost constant regardless of the positions ranging in the second direction; and an array of cylindrical lenses arranged on one of the first substrate and the second substrate, the cylindrical lenses extending in the first direction and arrayed in the second direction for separating incident light fluxes in the second direction, wherein, in each row of the sub-pixels arrayed in the second direction, the opening sections are arranged such that moving average values of positions of a center of gravity of the opening sections fluctuate within a range equal to or less than about 5 μm, where the moving average values are calculated by obtaining positions of the center of gravity of the opening sections taken along the first direction at a plurality of positions ranging in the second direction and by averaging the positions of the center of gravity within a spot width for each of the plurality of positions ranging in the second direction, and the spot width is a width of a converged light formed on the liquid crystal layer when a parallel light flux enters one of the cylindrical lenses.
