The long axes of the liquid crystal and the dichroic dye are both at an angle of 45 degrees with the reference plane (that is, the plane perpendicular to the first substrate). The liquid crystal and the reference plane are The normal angle of is also 45 degrees. Therefore, all non-polarized light can penetrate the liquid crystal dye layer, while vertically polarized light and horizontally polarized light will be partially absorbed by the liquid crystal dye layer.
