摘要： It is an object of the present invention to provide an information recording method for recording information in a data rewritable type optical recording medium having a plurality of information recording layers whereby a sufficiently high erasing efficiency can be ensured when data recorded in any one of the information recording layers are directly overwritten. In the information recording method according to the present invention, information is recorded in an optical recording medium 10 having at least a stacked L0 layer 20 and L1 layer 30 by projecting a laser beam thereonto via a light incidence plane 13a. In the case where information is to be recorded in the optical recording medium 10, information is recorded in the L0 layer 20 using an off-pulse recording format and information is recorded in the L1 layer 30 using an on-pulse recording format. As a result, even in the case of directly overwriting data recorded in either of the L0 layer 20 or the L1 layer 30, a sufficiently high erasing efficiency can be ensured.

摘要： A light source portion having laser light sources emitting red light, green light, and blue light and conventionally disposed integrally with the liquid crystal display panel is spatially separated from the liquid crystal display panel. Accordingly, the power supply, the optical system, and the heat source are incorporated into the light source portion and are thereby completely separated from the liquid crystal display panel. A laser beam emitted from the light source portion is guided to the liquid crystal display panel via a fiber. In this manner, it is possible to achieve a liquid crystal display device capable of significantly reducing the liquid crystal display panel in thickness and weight.
