1. A vertical alignment liquid crystal display module, comprising:
a vertical alignment liquid crystal display panel; and
an image color switch film disposed above or below the vertical alignment liquid crystal display panel, wherein the image color switch film has a following optical characteristic in various viewing angle directions having included angles of 60 degrees to 75 degrees with respect to a normal of the image color switch film:
an average transmittance of a visible light transmission spectrum of the image color switch film at an end of short wavelength is less than an average transmittance of a visible light transmission spectrum at an end of long wavelength.
