Display apparatus

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, and
• wherein 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.
