Zusammenfassung:Disclosed are a light guide plate and a backlight device including the same. The light guide plate according to an embodiment of the present invention includes a substrate for propagating a first light beam or a second light beam therein based on a total reflection effect, a prism pattern for separating the first light beam from the substrate in a 3D display mode; and a linear pattern for separating the second light beam from the substrate in a 2D display mode. Accordingly, the present invention can reduce the thickness of the backlight device by using one light guide plate. 도광판 및 이를 포함하는 백라이트 장치가 개시된다. 일 실시예에 따른 도광판은 전반사 효과에 기초하여 내부에서 제1 광빔 또는 제2 광빔을 전파하는 기판, 3D 디스플레이 모드에서 기판으로부터 제1 광빔을 이탈시키기 위한 프리즘 패턴과 2D 디스플레이 모드에서 기판으로부터 상기 제2 광빔을 이탈시키기 위한 선형 패턴을 포함할 수 있다.
