Abstract
A reflective liquid crystal display device comprises a transparent first substrate having formed thereon a transparent electrode, a first filter having a first color, and a second filte having a second color. A second substrate is disposed opposite and spaced-apart from the first substrate. A reflection layer is disposed on the second substrate. A polymer dispersed liquid crystal layer is disposed between the transparent electrode and the reflection layer and is formed by exposure to an ultraviolet ray in a preselected wavelength range. A ratio of a transmissivity of the first filter for the ultraviolet ray to a transmissivity of the second filter for the ultraviolet ray is 3.0 or less.
