<P>PROBLEM TO BE SOLVED: To prevent the generation of moire while reduction of front luminance is suppressed. <P>SOLUTION: A liquid crystal display apparatus comprises a liquid crystal display panel, a light source arranged on the back side of the liquid crystal display panel, a condensing optical sheet arranged between the liquid crystal display panel and the light source and having one major surface arranged continuously with a multiplicity of protrusions and recesses and a diffusion sheet interposed between the liquid crystal display panel and the optical sheet. The liquid crystal display is arranged to satisfy relation of (H/Tt)×(Pp/P)≥1.6 when an arrangement pitch of the protrusion and recesses of the optical sheet, the haze value of the diffusion sheet, the total ray transmittance of the diffusion sheet and the pixel pitch of the liquid crystal display panel are defined as P [μm], H [%], Tt [%] and Pp [μm], respectively. <P>COPYRIGHT: (C)2007,JPO&INPIT |
