Abstract
A light guide assembly, a total reflective display device and a method for manufacturing a light guide assembly are provided in the embodiments of the disclosure, the light guide assembly including: a first transparent adhesion layer, having a first profile formed thereon; a second transparent adhesion layer adhered to the first transparent adhesion layer and formed with a second profile corresponding to the first profile on a side of the second transparent adhesion layer adhered to the first transparent adhesion layer, the first profile and the second profile being formed to be in positive fit with each other and configured to incur light refraction at an interface therebetween of light rays being incident upon the first transparent adhesion layer from the second transparent adhesion layer to decrease an incident angle of the light rays; and a light guide panel, arranged on a side of the second transparent adhesion layer facing away from the first transparent adhesion layer.
