On the display area, a plurality of sub-pixelsR,G, andB whose colors are different from each other are repeatedly aligned in a determined alignment direction. A length L between both ends of the markin the alignment direction meets a relational expression of n×P+w≦L≦(n+1)×P−w (n is an integer of 0 or greater) where a width of the sub-pixel in the alignment direction is w and a pitch between the pixelsin the alignment direction is P.
