ABSTRACT:
An optical member according to one or more embodiments includes an optical plate and an optical film. In an embodiment, the optical plate includes an incident part receiving light provided from the exterior and an emitting part emitting the light. The optical film is attached to the incident part and includes a first conductive layer, a second conductive layer facing the first conductive layer and polarized particles disposed between the first conductive layer and the second conductive layer. Thus, light sources of a backlight assembly may be individually driven regardless of the type of light source and the disposition of the light sources, and image display quality may be improved by improving a contrast ratio by realizing various gradation voltages.
