Patent ID: 8908118

Claim:
A liquid crystal display device comprising a liquid crystal lens, a liquid crystal display panel, and a backlight, wherein the liquid crystal lens includes an upper substrate, a lower substrate, and a liquid crystal layer sandwiched between the upper substrate and the lower substrate, wherein the liquid crystal display panel includes a TFT substrate, an opposing substrate, a lower polarizing plate bonded onto the TFT substrate, an upper polarizing plate bonded onto the opposing substrate, and a liquid crystal layer sandwiched between the TFT substrate and the opposing substrate, wherein the liquid crystal lens is bonded onto the upper polarizing plate of the liquid crystal display panel with a bonding material or an adhesive material, wherein the upper substrate of the liquid crystal lens has a thickness larger than 0.2 mm and less than or equal to 1.5 mm and is thicker than the lower substrate of the liquid crystal lens; and wherein the thickness of the upper substrate of the liquid crystal lens is larger than a total of a thickness of the lower substrate of the liquid crystal lens, a thickness of the opposing substrate of the liquid crystal display panel, and a thickness of the upper polarizing plate of the liquid crystal display panel.
