PURPOSE:To provide the display correction plate for a liquid crystal display device which is used by joining the plate to the surface of the liquid crystal display device of a transmission type arranged with a back light behind the device and makes display easily recognizable from all diagonal directions by expanding the visual field angle to the entire direction through this plate. CONSTITUTION:Transparent spherical powders 2, 2... having a diameter of about 40mum are uniformly arranged on one surface of a transparent plate 1 to the high density of the extent that the adjacent powders come into contact with each other. Transparent plastic is used as the transparent plate 1 and similarly the spherical powders molded of the transparent plastic are used for the spherical powders 2, 2. The spherical powders 2, 2 arranged at the high density on the surface of the transparent plate 1 serve as optical diffusing parts. |
