Abstract
A monolithic diffuser plate for a backlight unit or a liquid crystal display (LCD) device can include a base substrate made of transparent glass, a monolithic diffusion sheet part integrated on a front surface of the base substrate, and a hiding diffusion part integrated on a rear surface of the base substrate for increasing a hiding power of the base substrate. The monolithic diffuser plate can increase a hiding power for hiding individual light sources in a backlight unit, prevent deformations caused by temperature variations and surrounding environmental factors, and minimize the thickness of a product using the monolithic diffuser plate while also increasing the reliability the product.
