PROBLEM TO BE SOLVED: To improve the color reproducibility of a liquid crystal display device sing a dyestuff-based polarizing plate. SOLUTION: The polarizing plate is provided which is formed by laminating a film with an optical compensating function on at least one surface of a polyvinyl alcohol-based resin film having dichroic dyestuffs adsorbed and aligned, and which has a 105 to 150°hue angle H and≤9 saturation C<SP>*</SP>when its parallel hue is represented on chromaticity coordinates (a<SP>*</SP>, b<SP>*</SP>). This polarizing plate has, preferably,≤3 saturation C<SP>*</SP>when orthogonal hue is represented on chromaticity coordinates (a<SP>*</SP>, b<SP>*</SP>). The film having the optical compensating function may be a film formed, for example, by coating a transparent base material with a liquid crystal compound. This liquid crystal compound may be, for example, discotic liquid crystal. When this polarizing plate is applied to a transmission type thin-film transistor liquid crystal display device, an image can be deterred from becoming yellowish. COPYRIGHT: (C)2004,JPO&NCIPI
