Patent ID: 8675154

Claim:
A liquid crystal display device, comprising: a liquid crystal display panel; a first polarizer between the liquid crystal display panel and a back light behind the liquid crystal display panel, the first polarizer including a first polarization film having a first transmission axis and a first phase-difference film having a first optical axis; a second polarizer in front of the liquid crystal display panel, the second polarizer including a second polarization film having a second transmission axis intersecting the first transmission axis, a second phase-difference film having a second optical axis intersecting the first optical axis, and a third phase-difference film having a third optical axis, the second phase-difference film being between the first and third phase-difference films and the second polarization film being between the second phase-difference film and the third phase difference film, and the third optical axis having an angular direction parallel to one of an angular direction of the first optical axis and an angular direction of second optical axis; and a substrate structure in front of the liquid crystal display panel and the second polarizer, the substrate structure including a third polarizer, the third polarizer including a fourth phase-difference film having a fourth optical axis intersecting the third optical axis.
