PURPOSE: A polymer dispersed liquid crystal display device is provided to minimize the refraction of the light emitted from a light source by using a second substrate having a low refractive index. CONSTITUTION: A first transparent electrode(110) is formed in the bottom surface of a 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 a second substrate. A light source(20) is formed in the bottom surface of the bonding layer. A low refractive index layer(400) is formed between the second substrate and the bonding layer.
