A reflective display device that is capable of improving a light efficiency in a reflective liquid crystal display in which a light is obliquely inputted from a peripheral light source or an auxiliary light source. In the device, an optical medium is provided with an inclined surface for refracting an incident light and refracting a light reflected from a reflective display part such that an obliquely inputted external light is vertically incident, to the reflective display part. Accordingly, it becomes possible to maximize a light efficiency of the reflective liquid crystal display at which a light is obliquely inputted from the peripheral light source or the auxiliary light source.
