Abstract
A liquid crystal display device includes a liquid crystal display panel, a first back light module (BLU), a polarizer, a second BLU and a pattern retarder. The first BLU is disposed below the liquid crystal display panel for emitting light. The polarizer is disposed on the first BLU, to convert the light into a first light. The second BLU is disposed between the liquid crystal display panel and the first BLU for emitting a second light. The pattern retarder is disposed between the liquid crystal display panel and the first BLU. The pattern retarder includes plural first and second polarizing regions with orthogonal polarization states, and the first and second polarizing regions are arranged in an interlaced order. Also, the polarization state of the first light is orthogonal to the polarization state of the second polarizing region.
