REFLECTIVE LIQUID CRYSTAL DISPLAY DEVICE
The present invention provides a reflective liquid crystal display device, which includes an upper substrate and a lower substrate that are opposite to each other, a liquid crystal layer arranged between the upper and lower substrates, a transparent plastic layer bonded to a surface of the lower substrate that is distant from the liquid crystal layer, and a mirror-reflection layer that is attached by the transparent plastic layer to the surface of the lower substrate.
