Abstract:
A light path control device and an electronic device including the light path control device, which reduce color shift at a side viewing angle, are provided. The light path control device can include a light path control layer including first, second and third light control layers, and a transparent base member coupled to the first light control layer or the third light control layer. The third light control layer can have a refractive index which is lower than a refractive index of the second light control layer. The light path control layer can include a first refractive surface disposed between the first light control layer and the third light control layer, and a second refractive surface and a third refractive surface disposed between the second light control layer and the third light control layer.
