The present invention provides a retardation element capable of ensuring that, even when the retardation element is incorporated into a display element having pixels, each pixel being a triad of red, green and blue display sections, the display element shows excellent display characteristics. A retardation film includes a glass substrate, and a liquid crystal layer made from a polymerizable liquid crystalline material, formed on an alignment layer that has been formed on top of the glass substrate. The retardation film is for use in a liquid crystal display element having pixels, each pixel being a triad of red, green and blue display sections, and the liquid crystal layer has a plurality of fine areas that have been created, by patterning, correspondingly to the display sections of the pixels in the three colors. These fine areas are made from one liquid crystalline material, and have different thicknesses so that they have different retardation values depending upon the wave range of light that passes through them.

There are provided a liquid crystal display device, which positively reflects, by a reflecting electrode and a light-shielding layer, light emitted from a backlight and further reflected from a light-shielding layer or a reflecting layer, and recycles the light while avoiding absorption in a linearly polarizing plate to improve the utilization efficiency of light and thus to realize a bright display screen, and an optical element for use in the liquid crystal display device. The liquid crystal display device comprises: a polarizer for converting light emitted from a back light source to linearly polarized light; a reflecting layer comprising a reflection area part for reflecting the linearly polarized light converted by the polarizer and a transmission area part for transmitting the linearly polarized light converted by the polarizer; and at least one phase difference plate which is disposed so that only the light transmitted through the transmission area part after conversion of the light source-derived light to the linearly polarized light by the polarizer is incident to the phase difference plate.

摘要:
A process for removal and conversion into sulfur of hydrogen sulfide in a gaseous or liquid material which comprises essentially treating the said material with a nitrohumic acid or its salt prepared by treating humic acid with a nitrating agent and, if necessary, converting the resultant into an alkaline salt. The process is advantageous essentially in that hydrogen sulfide can be removed economically and converted into sulfur, and that the desulfurization agent, i.e. a nitrohumic acid or its salt is non-toxic and non-corrosive.
