1. A display apparatus comprising:
- a backlight assembly configured to emit light; and
a display panel configured to display a two-dimensional (2D) image or a three-dimensional (3D) image using the light,wherein the display panel comprises;
a liquid crystal panel;
a first polarizing panel disposed between a first surface of the liquid crystal panel and the backlight assembly; and
a second polarizing panel disposed on a second surface of the liquid crystal panel,wherein the backlight assembly comprises;
a first backlight unit configured to emit light for creating the 2D image;
a second backlight unit configured to emit light for creating the 3D image; and
a third polarizing panel disposed between the first backlight unit and the second backlight unit, and configured to prevent at least a portion of leakage light leaking from the second backlight unit from being incident to the second backlight unit,wherein the second backlight unit comprises;
a second light guide plate; and
a second light source unit disposed along a lateral side of the second light guide plate, and configured to emit light to the second light guide plate,wherein the third polarizing panel comprises a plurality of barriers arranged at regular intervals on a surface of the third polarizing panel, the plurality of barriers being configured to reflect and scatter incident light regardless of a polarizing axis orientation of the incident light,wherein the light reflected by the plurality of barriers includes the light to create the 3D image, and is emitted to the second backlight unit, andwherein a polarizing axis of the first polarizing panel is orthogonal to a polarizing axis of the second polarizing panel, and is identical to a polarizing axis of the third polarizing panel of the backlight assembly.
