Abstract
A liquid crystal display, optical sheet manufacturing method, and an optical sheet are provided. The occurrence of moiré is prevented while suppressing a reduction in front luminance. The liquid crystal display includes: a liquid crystal display panel; a light source arranged on a back surface side of the liquid crystal display panel; an optical sheet with a light-condensing property arranged between the liquid crystal display panel and the light source, the optical sheet having a number of irregularities arranged continuously on a principal surface of the optical sheet; and a diffuser sheet arranged between the liquid crystal display panel and the optical sheet. The liquid crystal display is constructed so that when an arrangement pitch of the irregularities of the optical sheet is P [μm], a haze value of the diffuser sheet is H [%], a total light transmittance of the diffuser sheet is Tt [%], and a pixel pitch of the liquid crystal display panel is Pp [μm], the following relationship is satisfied: (H/Tt)·(Pp/P)≧1.6.
