Backlight unit and method of manufacturing diffuser employed in the backlight unit |
摘要 |
A luminous backlight unit designed to compensate for a difference in distribution of light output on an output surface of a light guiding panel, and a method of manufacturing a diffuser employed in the backlight unit. The backlight unit includes: one or more light sources that emit light; a light guide panel which guides the propagation of light incident through a side edge thereof and has a light-emission surface; a holographic pattern provided on a surface of the light guide panel, for converting the incident light into a surface light and outputting the converted surface light to the light-emission surface; and a diffuser disposed facing the light-emission surface, for diffusing the emitted light from the light-emission surface and is characterized in that distribution of diffusion angles is varied as it goes from a point close to the light source to a point distant from the light source.
