Abstract: A light guide device includes N+1 light guide plates and N linear plane splitters. The light guide plates include a light outlet face, a light guiding face and a reflection face. The volume of the light guide device is defined by the light outlet face opposite to the light guiding face. The light guiding face has a plurality of first microstructures for diverting the light. The reflection face extends from the light outlet face toward a splitting portion. The linear plane splitters have a first and a second splitting portion. The first and second splitting portions of the ith linear plane splitter connects the light guiding face and the reflection face of the (j−1)th and jth light guide plates. The i and j satisfy 1≦i≦N and 2≦j≦N+1. Moreover, a light module utilizing the light guide device is disclosed.
