Double-sided emission type display device

A display device comprising:

• a first display panel and a second display panel arranged separately from each other;
• and
• a backlight between the first display panel and the second display panel and configured to supply light to the first display panel and the second display panel,
• wherein the backlight comprises:
• a plurality of Printed Circuit Boards (PCBs) each shaped as a bar elongated in a first direction and arranged in parallel in a second direction perpendicular to the first direction;
• a plurality of Light Emitting Diodes (LEDs) arranged on different sides of the plurality of PCBs;
• a first chassis that covers the first face of the plurality of PCBs and a second chassis that covers the second face of the plurality of PCBs;
• and
• a plurality of lenses respectively for the plurality of LEDs and configured to guide light generated from the plurality of LEDs,
• wherein a first plurality of LEDs, among the plurality of LEDs, on a first face of the plurality of PCBs and a second plurality of LEDs, among the plurality of LEDs, on a second face of the plurality of PCBs are arranged to not overlap one another,
• wherein the first chassis comprises a first plurality of through holes at locations that correspond to the first plurality of LEDs, and the second chassis comprises a second plurality of through holes at locations that correspond to the second plurality of LEDs,
• wherein the first plurality of through holes and the second plurality of through holes each have a shape corresponding to the plurality of lenses and each have a diameter larger than or equal to a diameter of the plurality of lenses, and
• wherein the first chassis and the second chassis are flat boards that support the plurality of PCBs.
