The utility model relates to a polymer dispersed liquid crystal thermosensitive dimming temperature card. The temperature card is composed of two transparent films, a plurality of polymer dispersed liquid crystal film sheets arranged in sequence and a transparent plastic sheet marked with temperature scale values, liquid crystals in the polymer dispersed liquid crystal film sheets arranged in sequence have different clearing point temperatures and are arranged according to the clearing point temperature values. The cholesteric liquid crystal thermochromic display temperature card has the samefunctions as the existing cholesteric liquid crystal thermochromic display temperature card; the temperature indicating card has different appearance visual effects, can be large and small in temperature interval, is simple in manufacturing method and low in cost, can be used as a non-electronic and portable temperature indicating card (such as water temperature display in a vacuum cup) with wideapplication range, can be
