摘要：
This invention provides an acrylic resin containing film, which is transparent and highly heat resistant and has significantly improved brittleness, and a polarizing plate using the acrylic resin containing film. Further yield in punching work and laminating work of the polarizing late is improved and a liquid crystal display device which can maintain good visibility in long term use is also provided by the polarizing plate. The acrylic resin containing film is composed mainly of an acrylic resin and is characterized in that the film contains the acrylic resin and the cellulose ester resin in a weight ratio of 51:49 to 95:5 and further contains a retardation control agent.
