Several types of liquid crystal devices need polarizers to be able to perform their function properly. The plastic sheet polarizers used for this application are fairly complex layer systems and, more often than not, the problems that result from a wrong understanding of the nature of polarized light or from inappropriate handling of the material are underestimated. This paper is a summary of the properties and construction of plastic sheet polarizers. It explains why the various layers are there and how the user can check quickly if the material he receives does satisfy his needs.
