Abstract
The object is to provide a display device with a superior viewing angle. The display device includes a display portion, a liquid-crystal barrier portion, first to third polarizing layers, and at least one viewing-angle compensation layer. The liquid-crystal barrier portion is disposed on one side of the display portion, and adjusts an intensity of light of the display portion. The first polarizing layer is disposed opposite to the liquid-crystal barrier portion relative to the display portion. The second polarizing layer is interposed between the display portion and the liquid-crystal barrier portion. The third polarizing layer is disposed opposite to the display portion relative to the liquid-crystal barrier portion. The viewing-angle compensation layer is interposed between the liquid-crystal barrier portion and the third polarizing layer, and no viewing-angle compensation layer is interposed between the second polarizing layer and the liquid-crystal barrier portion.
