Patent ID: 8687273

Claim:
An image display device comprising: a display panel having a first group of pixels for displaying a first image and a second group of pixels for displaying a second image; and a parallax barrier element for separating display light emitted from the first group of pixels and display light emitted from the second group of pixels, the parallax barrier element including a plurality of light-shielding portions and a plurality of light-transmitting portions which are alternately positioned within a same plane, wherein, the parallax barrier element includes converging elements respectively provided for the plurality of light-transmitting portions, said converging elements are lenses each including (i) a curved side and (ii) a substantially flat side, and wherein the curved side faces a backlight of the display device and the substantially flat side faces a viewer of the display device; and a resin layer which is in contact with a surface of each lens that is closer to the display panel, wherein, a refractive index of the lenses and a refractive index of the resin layer are different, wherein the refractive index of the lenses is higher than the refractive index of the resin layer; and wherein a thickness of the resin layer is greater than a thickness of the lenses.
