The present disclosure relates to a backlight unit and a liquid crystal display device having a backlight unit. The backlight unit includes a light guide plate, a light source assembly positioned adjacent to a light-incident surface among lateral surfaces of the light guide plate, and an external tape covering the entire lateral surface of the light guide plate except the light-incident surface and parts of an upper surface and a lower surface of the light guide plate. Thus, the light efficiency of the backlight unit may be increased and the manufacturing costs reduced. Further, since the light efficiency of the backlight unit is increased, the luminance and power consumption of the liquid crystal display device can be improved.

The present disclosure relates to a method for manufacturing the patterned retarder used in the three-dimensional display device. The present disclosure suggests a method for manufacturing a patterned retarder comprising: defining a first retarder region and a second retarder region in the patterned retarder; forming a first polarization pattern at the first retarder region by a partial exposure process having a first exposure energy; and forming a second polarization pattern at the second retarder region by whole exposure process having a second exposure energy. By manufacturing the patterned retarder with lower exposure energy, it is possible to reduce the whole manufacturing takt time, so that the production yield can be enhanced and the production cost can be reduced.
