PURPOSE: A polymer dispersed liquid crystal display is provided to improve a contrast ratio by filtering an unnecessary non-parallel ray before an incidence to a polymer dispersed liquid crystal(PDLC). CONSTITUTION: A thin film transistor and an active switch element consisting of an active circuit part(210) and a pixel electrode(220) are formed on a back plate(200). A black mask(110) and a common electrode(120) are formed on a front plate(100). A twist nematic liquid crystal(TNLC) layer(300) is prepared between the front plate(100) and the back plate(200). The TNLC layer(300), the active circuit part(210), the pixel electrode(220), and the common electrode(120) form a light control part. A light interruption layer(120) is formed on the front plate(100) so as to interrupt a ray incident to a region beyond the pixel region.
