Abstract: PROBLEM TO BE SOLVED: To provide a reflection type guest-host liquid crystal display(LCD) device realizing high contrast ratio and high reflectance and having a low price and a simple structure. SOLUTION: The reflection type liquid crystal display device has a first transparent substrate, a first electrode means disposed on one surface of the first transparent substrate, a second transparent substrate having a first surface and a second surface and a second electrode means disposed on the first surface of the second transparent substrate. The first and the second electrode means are opposed to each other and the first and the second transparent substrates are arranged so that a space is generated between the first and the second electrode means and a guest-host liquid crystal layer is disposed at the space. The first and the second electrode means regulate plural pixel positions and reflection units each having a triangular pyramid shape are respectively disposed in plural pixel positions on the second surface of the second transparent substrate.
