Abstract: The present invention is designed to provide a liquid crystal display device in which a nontacky silicone sheet having rubber elasticity is so provided between a liquid crystal display panel and a transparent protection plate for protecting the liquid crystal display panel as not to form any air layer and a method for producing such a liquid crystal display device.

Abstract: This invention relates to a method of producing a molded transparent covering member. The steps of the method comprise providing a silicon rubber material and a fluorescent substance together to form a material to be molded in a space between an inner surface of an upper mold and an outer surface of a lower mold; sand-blasting at least one of the inner surface of said upper mold and the outer surface of the lower mold; and injecting the material into the space formed between upper mold and the lower mold.

Abstract: An LED device is provided that has an excellent color rendering property and no toxicity and does not increase production costs more than necessary. A covering member is also provided used for such a device. The LED device comprises a light-emitting element for emitting light in a blue to green region and a fluorescent substance containing a red phosphor for converting the wavelength of the light emitted from the light-emitting element to another wavelength. The red phosphor is CaS activated by Eu or a phosphor expressed by the general formula AEu(1−x)LnxB2O8, wherein A is an element selected from the group consisting of Li, K, Na and Ag; Ln is an element selected from the group consisting of Y, La and Gd; and B is W or Mo; and x is number equal to or larger than 0, but smaller than 1.

Abstract: This invention relates to a transparent coating member mountable on a light-emitting diode including a fluorescent substance and a light diffusion substance including calcium carbonate in order to reduce color variation at various locations of a transparent coating member and also reduce manufacturing costs of the transparent coating member without significantly lower the level of chromaticity. Furthermore, this invention relates to a transparent coating member mountable on a light-emitting diode (LED) including a fluorescent substance and a light storing pigment. This structure allows an exhibition of afterglow of the transparent coating member after turning off the light in a room so that locating the position of the transparent coating member is made easier thereafter. The light diffusion substance and the light storing pigment can be added to the transparent coating member to acquire both advantages derived from respective substances.
