Vertical alignment liquid crystal display module comprising an image color switch film having an average transmittance of a visible light spectrum for short and long wavelengths of the visible light
Abstract:
A vertical alignment liquid crystal display module including a vertical alignment liquid crystal display panel and an image color switch film is provided. The image color switch film is disposed on the vertical alignment liquid crystal display panel. 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, the image color switch film has a following optical characteristic: an average transmittance of a visible light transmittance spectrum of the image color switch film at an end of short wavelength is less than an average transmittance of the visible light transmittance spectrum of the image color switch film at an end of long wavelength.
