PURPOSE: A polymer dispersed liquid crystal display device is provided to reduce the angle of refraction of the light passing through a polymer dispersed liquid crystal display part by using a high refractive index layer formed in a first or a second substrate. CONSTITUTION: A first transparent electrode(110) is formed in the bottom surface of the first substrate(100). Polymer dispersed liquid crystal(300) is formed in the bottom surface of the first transparent electrode. A second transparent electrode(210) is formed in the bottom surface of the polymer dispersed liquid crystal. A second substrate(200) is formed in the bottom surface of the second transparent electrode. A bonding layer(50) is formed in the bottom surface of the second substrate. A light source(20) is formed in the bottom surface of the bonding layer. A high refractive index layer(400) is formed in the upper part of the second substrate and between the bonding layer and the first substrate.
