<P>PROBLEM TO BE SOLVED: To provide a means for preventing the problem that a center part of an optical diffusion plate is bent in a spherical shape to the side of a liquid crystal display panel by thermal expansion, an optical sheet set of a soft member disposed between the optical diffusion plate and the liquid crystal display panel is pushed to the liquid crystal display panel side and abuts on the liquid crystal display panel and thereby [a Newton ring] is generated in a display image and display quality is reduced. <P>SOLUTION: In a liquid crystal display provided with the liquid crystal display panel 2, the optical diffusion plate disposed on the rear surface of the liquid crystal display panel 2 and a backlight unit for performing irradiation with light from the rear surface of the liquid crystal display panel 2, the optical diffusion plate is formed in a spherical shape which is curved to the backlight unit side in a projecting shape and a gap is provided between tip parts of supporting columns whose heights are changed along the spherical shape of the spherical optical diffusion plate 12 and the rear surface of the spherical optical diffusion plate 12. <P>COPYRIGHT: (C)2007,JPO&INPIT |
