Abstract: Object of the present invention is to provide an acrylic-resin-containing film which exhibits high transparency, high heat resistance, and markedly improved brittleness, a polarizing plate using the acrylic-resin-containing film which improves a yield of operation such as punching of a polarizing plate or bonding panels and a liquid crystal display device which can keep to exhibit excellent visibility in long-terms usage in harsh environment. These objects have been achieved by the acrylic-resin-containing film comprising a acrylic resin (A) and a cellulose ester resin (B), or comprising the acrylic resin (A), the cellulose ester resin (B) and at least a resin (D) which is other than the resins (A) and (B) and has a glass transition temperature Tg of 120-300° C. The film is characterized in that it has a haze of less than 2%, a tensile softening point of 120-150° C. and undergoes no ductile fracture.
