Abstract: A wavelength converter and a liquid crystal display having the same, the wavelength converter including a first pattern that converts a wavelength of light into red light, and a second pattern that converts a wavelength of light into green light. The first pattern and the second pattern are alternately disposed, and an optical path length La of each of the first pattern and the second pattern is given by Equation (1): La=(λa/2)×m, wherein La is an optical length of an a-th pattern, λa is a wavelength of light converted by the a-th pattern, a is one or two, and m is a natural number.
