Abstract
A dual display liquid crystal display (LCD) device includes a front light unit for supplying a light, a first polarizing plate disposed on the front light unit, a first phase compensation film disposed on the first polarizing plate, an LCD panel disposed on the first phase compensation film, a selective reflection/transmission unit disposed on the LCD panel, a second phase compensation film disposed on the selective reflection/transmission unit, and a second polarizing plate disposed on the second phase compensation film, wherein the selective reflection/transmission unit selectively reflects and transmits the incident light so that the dual display LCD device operates in reflection mode to display an image on a front side thereof in a first display mode and operates in a transmission mode to display an image on a rear side thereof in a second display mode.
