Abstract: A prism sheet having an excellent wet-out property and an LCD(Liquid Crystal Display) by using the same are provided to minimize a spot phenomenon due to the moisture and to shorten the thickness of a light guide panel through the removal of a diffuser. The prism sheet has a light refraction member formed at the other surface of a base film(300) having a flat surface(301). Plural unit prism(310) is arrayed on the light refraction member in a direction. The base film is a base layer of the prism sheet and made of transparent materials. The light refraction member refracts the light passing through the base film so that the light beam has a constant orientation. The light refraction member is integrally formed with the base film. The ridge lines of the plural unit prisms are inclined with the constant gradient. The gradient is gradually changed with the lapse of time so that a gradient change point(304) is defined. The positions of the gradient change points are irregularly arrayed.
