Abstract
A polymer dispersed liquid crystal film comprises: a first substrate () and a second substrate () arranged opposing to each other; a first transparent conductive film () and a second transparent conductive film () arranged on opposing surfaces of the first substrate () and the second substrate (), respectively; and a polymer dispersed liquid crystal layer () located between the first transparent conductive film () and the second transparent conductive film (), wherein the polymer dispersed liquid crystal layer () comprises homogeneously dispersed bi-axis liquid crystal () and polymer (). When no voltage is applied between the first transparent conductive film () and the second transparent conductive film (), the bi-axis liquid crystal () exhibits a random arrangement, and the bi-axis liquid crystal () has perpendicular refractive index (n) and the parallel refractive index (n), wherein the perpendicular refractive index (n) and the parallel refractive index (n) are not equal to each other, and neither of them matches the refractive index of the polymer (n). A method of preparing a polymer dispersed liquid crystal film and a display apparatus comprising a polymer dispersed liquid crystal film are also disclosed.
