A front light guide includes a light guide plate, a light source, a functional material layer and a first adhesive layer. The light guide plate has a side surface, a first surface and a second surface opposite to the first surface. The light guide plate has a first refractive index. The light source faces the side surface and configured to emit light into the light guide plate. The functional material layer is disposed at a side adjacent to the first surface, and has a third refractive index. The first adhesive layer is interposed between the light guide plate and the functional material layer so as to adhere the light guide plate with the functional material layer. The first adhesive layer has a second refractive index. The first refractive index is greater than the second refractive index, and the second refractive index is greater than the third refractive index.

Front light guide module and electrophoresis display having the same

A display device including a reflective display panel, a plurality of electrical or optical element layers, and at least one light-emitting element is provided. The electrical or optical element layers are stacked above the reflective display panel. One of the electrical or optical element layers is a light guide plate. The light-emitting element is disposed beside the light guide plate. A plurality of transparent medium layers are respectively located between every two adjacent ones of the reflective display panel and the electrical or optical element layers and above the electrical or optical element layer most away from the reflective display panel among the electrical or optical element layers. At least one of the transparent medium layers above the light guide plate is a gas layer.
