Abstract
An integrated touch module and a touch display device are provided. The integrated touch module has a touch sensing structure formed on a polymer film. The polymer film, a liquid crystal phase retardation layer, and a linear polarizing layer constitute a circular polarizing element. The average reflectance of the circular polarizing element in the visible light range is less than 5%, and the standard deviation of the reflectance is less than 0.2%. The touch display device includes the integrated touch module.
