Disclosed herein are a flat panel display which is capable of reducing consumption of standby power, and a method for driving the same. The flat panel display includes a display unit for displaying an image, a driving circuit for controlling driving of the display unit, a receiver for receiving a user command, and a power supply unit for setting a power mode to a driving mode or a standby mode according to a predefined power setting or the user command, and supplying driving power to the display unit, driving circuit and receiver in the driving mode and only to the receiver in the standby mode. When the power mode is set to the standby mode, the power supply unit generates the driving power using a battery contained therein and supplies the generated driving power to the receiver, and cuts off input of external power.

A backlight unit for a liquid crystal display panel includes a diffusor that diffuses light emitted from a front surface thereof, a reflective plate that reflects light toward a rear surface of the diffusor; and a collimator that collimates the light emitted from the front surface of the diffusor toward the liquid crystal display panel. The collimator includes a base layer that refracts the diffused light from the diffusor toward the liquid crystal panel, a collimating layer of lenses disposed along two perpendicular directions on a front surface of the base layer, and a reflective pattern on a rear surface of the base layer along a boundary of each of the lenses, the reflective pattern exposing an aperture portion of the base layer facing each of the lenses.
