<P>PROBLEM TO BE SOLVED: To provide a liquid crystal display device with improved viewing-angle contrast. <P>SOLUTION: A liquid crystal display device includes a first polarization film (16), an optical compensation film (F) including a first retardation region (20) and a second retardation region (22), a first substrate (12), a layer (10) including a medium changing from optical isotropy to optical anisotropy or from optical anisotropy to optical isotropy by application of an electric field, and a second substrate (14) in this order. The slow axes of the first retardation region and the second retardation region are in parallel to each other, the second retardation region has an Re (550) of 20 nm or less and has an Rth (550) of 20 nm to 120 nm, and the first retardation region includes a retardation layer containing a discotic liquid crystal compound fixed in an aligned state. <P>COPYRIGHT: (C)2012,JPO&INPIT |
