An image display device comprising: a display element including a plurality of units of display each comprising at least a first sub pixel that transmits light for a first view point and a second sub pixel that transmits light for a second view point; an optical unit that distributes the light from the first sub pixel and light from the second sub pixel into the first view point and the second view point, respectively; a plurality of data lines extending in a first direction in which the first sub pixels and the second sub pixels are alternately arrayed; and a plurality of gate lines extending in a second direction, the second direction being orthogonal to the first direction and being a direction in which the first sub pixels and the second sub pixels are homogeneously arrayed, wherein a direction in which the optical unit distributes light is along the first direction, wherein when a pair of adjoining first sub pixels and a pair of adjoining second sub pixels are each defined as an adjoining-pixel pair (4PAIR, 4PAIR2), the adjoining sub pixels adjoin each other in the second direction with one data line of the plurality of data lines therebetween, the adjoining sub pixels of the adjoining-pixel pair (4PAIR, 4PAIR2) have respective switching elements, the switching elements being commonly connected to the data line disposed between the adjoining sub pixels, and controlled by different gate lines of the plurality of gate lines, the adjoining sub pixels being commonly provided with a storage capacitor electrode, for each switching element one electrode connected to the switching element, and the storage capacitor electrode form a capacitor, the storage capacitor electrode is arranged at least at a boundary region between the adjoining sub pixels, K number of storage capacitor lines electrically connected to the storage capacitor electrode are each arranged so as to traverse at least one of virtual lines (B-B') each parallel to the second direction and evenly dividing the area of each of the first sub pixels and each of the second sub pixels into K+1 pieces. a display element including a plurality of units of display each comprising at least a first sub pixel that transmits light for a first view point and a second sub pixel that transmits light for a second view point; an optical unit that distributes the light from the first sub pixel and light from the second sub pixel into the first view point and the second view point, respectively; a plurality of data lines extending in a first direction in which the first sub pixels and the second sub pixels are alternately arrayed; and a plurality of gate lines extending in a second direction, the second direction being orthogonal to the first direction and being a direction in which the first sub pixels and the second sub pixels are homogeneously arrayed, wherein a direction in which the optical unit distributes light is along the first direction, wherein when a pair of adjoining first sub pixels and a pair of adjoining second sub pixels are each defined as an adjoining-pixel pair (4PAIR, 4PAIR2), the adjoining sub pixels adjoin each other in the second direction with one data line of the plurality of data lines therebetween, the adjoining sub pixels of the adjoining-pixel pair (4PAIR, 4PAIR2) have respective switching elements, the switching elements being commonly connected to the data line disposed between the adjoining sub pixels, and controlled by different gate lines of the plurality of gate lines, the adjoining sub pixels being commonly provided with a storage capacitor electrode, for each switching element one electrode connected to the switching element, and the storage capacitor electrode form a capacitor, the storage capacitor electrode is arranged at least at a boundary region between the adjoining sub pixels, K number of storage capacitor lines electrically connected to the storage capacitor electrode are each arranged so as to traverse at least one of virtual lines (B-B') each parallel to the second direction and evenly dividing the area of each of the first sub pixels and each of the second sub pixels into K+1 pieces.
