A light-polarizing film with high permeability for improving an interference light of a color organic light emitting diode (OLED), wherein a phase retardation plate is disposed on the color OLED for transforming light phase, and the light-polarizing film is disposed on the phase retardation plate for absorbing the projective light. The polarization degree of the light-polarizing film is between 15% and 93%, the corresponding permeability is between 46% and 80%, whereby the light-polarizing film with high permeability is utilizes to acquire necessary light-polarizing effect of emitting light of the color OLED itself, the color OLED doesn't need to increase power, and the color OLED can keep original economical lifetime. Furthermore, the incident external interference light is partly absorbed by the light-polarizing film; and the phase the incident external interference light is transformed by the phase retardation plate, the external interference light is reflected by the color OLED to be reflected light, the reflected light is transformed by the phase retardation plate again, and the reflected light is mostly absorbed by the light-polarizing film so as to improve the interference light.
