摘要： In a liquid crystal display device configured so that ambient light is collected and the collected ambient light is guided to the back of a liquid crystal panel so as to illuminate the liquid crystal panel, a light-collecting unit 17 and a light-guiding unit 18 are provided. The light-collecting unit 17 collects and captures ambient light, and converts the ambient light into a transmitting light which transmits in the light-collecting unit 17. The light-guiding unit 18 connected to the light-collecting unit 17 redirects a light path of the transmitting light from the light-collecting unit 17 so that the transmitting light proceeds to the back of a liquid crystal panel 15. Thus, unlike conventional light-collecting units, a light-collecting unit of the invention is composed of two separated units, one being a light-collecting unit for converting ambient light into a transmitting light and the other being a light-guiding unit for guiding the transmitting light to the liquid crystal panel. This configuration attains an increase in an occupied area of the light-collecting unit and thereby achieves an increased brightness of the liquid crystal display device.

摘要： A method of making a polymer dispersion type liquid crystal display element including a phase separation step. The method calls for placing a liquid crystal polymer precursor compatible solution having a liquid crystal and a polymer precursor between a pair of substrates, each having an inside electrode, and irradiating a substrate surface with ultraviolet. The radiation causes a phase separation of the liquid crystal and the polymer precursor as well as polymerization and curing of the precursor. The method forms a polymer dispersion type liquid crystal having liquid crystal droplets dispersed and held in a continuous matrix phase or a three-dimensional network matrix. During the phase separation step, the irradiation time is controlled from the beginning of irradiation to the completion of phase separation to influence any of the degree of polymerization of the precursor in the solution, the rate of phase separation, and the generating density of the separated liquid crystal nuclei so that the dispersed liquid crystal droplets have even particle sizes.

摘要： In a liquid crystal display element in which liquid crystal droplets are dispersed and held in polymer composition sandwiched between a pair of substrates each having an electrode at the inside thereof, the liquid crystal droplets are formed to have substantially the same shape and size with minimized variations in particle size so that the liquid crystal droplets can be stably kept in the bipolar-form orientation pattern within a wide temperature range, to minimize hysteresis of transmittance of light to a voltage applied across the electrodes. Similar effects can be produced by tilt angles of liquid crystal molecules in the vicinity of interface between the liquid crystal droplets and the polymer compound being minimized or by anchoring strength being increased, by adding an interfacial restrictive force controlling material to a liquid crystal polymer precursor compatible solution or raising a temperature under which polymerization of polymers and phase separation between the polymer and the liquid crystal are performed by irradiation of ultraviolet. Also, an improved response to electric field can be provided within a wide operation temperature range by allowing surface tension of liquid crystal material to be smaller than critical surface tension of an insulating film or surface tension of the polymer compound. Accordingly, the liquid crystal display element is available for forming displays, such as television sets and personal computers, capable of displaying moving pictures and the like within a wide operation temperature range.
