Abstract
Due to lights with different wavelengths having different indexes of refraction in a liquid crystal, a retardation between lights with different wavelengths occurs and causes the problem of viewing angle of the liquid crystal display. The present invention provides a manufacturing method of light-guiding apparatus of a liquid crystal display to form light-guiding pillars having a characteristic of total reflection as a fiber. The light from back light module through the light-guiding pillars enters the liquid crystal at an incident angle smaller than 150 for reducing the retardation between lights with different wavelengths.
