The present invention relates to a dual liquid crystal display device. By forming a prism which is geared with a light entering surface and a light exiting surface, individually, of a light guide plate of each liquid crystal display device, light is guided from one light source to two light guide plates when used as being assembled, and the light is reflected by the prism of the light exiting surface when used as being separated. Therefore, light efficiency can be improved. 본 발명은 듀얼 액정표시소자에 관한 것으로, 각각의 액정표시소자의 도광판의 출광면 및 입광면에 각각 치합하는 프리즘을 형성하여 조립하여 사용할 때는 하나의 광원으로부터 2개의 도광판에 광이 인도되로고 하고 분리하여 사용할 때는 출광면의 프리즘에 의해 광이 반사되도록 함으로써 광효율을 향상시킨다.
