摘要： The present invention relates to a backlight apparatus and a liquid crystal display apparatus, capable of realizing a backlight apparatus having high color reproductivity without color irregularities in a backlight apparatus having a LED device as its light source. In the optical unit 61, there are disposed the dichroic mirror B which transmits green light Lg and red light Lr and reflects blue light Lb, the dichroic mirror G which transmits the light Lb and the light Lr and reflects the light Lg, and the dichroic mirror R which transmits the light Lb and the light Lg and reflects the light Lr, and they transmit or reflect the light emitted from the LED devices 11B, 11G and 11R to mix to form the white light Lw. The light Lw formed by the dichroic mirrors B, G and R is entered to the light guiding plate 62 by the mirror performing a total reflection. Therefore, in the backlight apparatus having an LED device as its light source, it is possible to realize a backlight apparatus having high color reproductivity, without color irregularities.

摘要： A color filter (19) used in a transmissive color liquid crystal display panel of a color liquid crystal display (LCD) apparatus. This color filter (19) is constituted by a tristimulus color filter for wavelength-selecting and transmitting red light, green light and blue light. Mixing of blue color and red color is prohibited by not having the transmission wavelength band of the red filter CFR overlaid substantially on the transmission wavelength band of the blue filter CFB.

摘要： A light dimming dot pattern is provided for an LCD in which the diameter of dots is changed in a range from approximately 0.16 mm to approximately 0.65 mm depending on the distance of the dots from a fluorescent tube (13) in such a manner that the volume of the shielded light is increased and decreased at a location close to a position overlying the fluorescent tube (13) and at a location remote from the fluorescent tube (13), respectively. In this manner, a light dimming dot pattern with a transmittance for all light rays of approximately 62% (roughly in the vicinity of 62%), higher than the transmittance for all light rays in the conventional technique not higher than 50%, is produced. Consequently, the light of uniform high luminance may be produced without raising the luminance of the fluorescent tube (13), and hence an LCD of high luminance may be realized.

摘要翻译： 提供了一种用于LCD的点亮调光点图形，其中点的直径在大约0.16mm至大约0.65mm的范围内变化，这取决于点与荧光管（13）的距离，使得体积 在靠近荧光管（13）的位置和远离荧光管（13）的位置处，屏蔽光的距离增加和减小。 以这种方式，产生对于常规技术中不大于50％的所有光线的透射率高于大约62％（大致在62％附近）的所有光线的透光率的光调光点图案 。 因此，可以在不提高荧光管（13）的亮度的情况下产生均匀高亮度的光，因此可以实现高亮度的LCD。

摘要： The present invention relates to a backlight and a light guide plate, a method of manufacturing a diffuser and the light guide plate, and to a liquid crystal display apparatus, all enabling a cost reduction by reducing the parts count and curtailing unnecessary manufacturing processing. A diffuser 261 has a light distribution layer 181 including a prismatic surface wherein stripe grooves or asperities are arrayed in parallel with each other, a diffusion layer 182 containing diffusion elements 191 for diffusing incident light, and a light incidence control layer 271 including a prismatic surface wherein stripe grooves or asperities are arrayed in parallel on a side of fluorescent tubes 131. The diffusion layer 182 is formed from the same resin, and only the diffusion elements 191 are formed from a different resin. The prism of the light incidence control layer 271 is optimized so as to enhance the proportion, to light being reflected without entering the light incidence control layer 271, of light re-entering other parts of a surface of the light incidence control layer 271, in order to guide incident light toward the diffusion layer 182 efficiently. The present invention is applicable to a backlight of a liquid crystal display apparatus.
